Hey! There Are Cockroaches in my Chocolate Ice Cream! (Part 4/4)

At the end of the presentation, Dr. Schwarcz demonstrates a reaction where he reacts calcium carbide with water to produce flammable gas- acetylene. When a burning splinter was introduced through a tiny opening, an explosion in the flask took place. However, when the same experiment was repeated, by introducing a burning splinter in a tiny opening in the flask, the flask acted as a lamp due to absence of oxygen. The moral of the whole exhibition was that the same thing used for explosion could also be used as a lamp. It completely depends on the way one uses the knowledge one possesses.

The End :)

Hey! There Are Cockroaches in my Chocolate Ice Cream! (Part 3/4)

Later on in the presentation, Dr. Schwarcz introduced his firm and its objectives, which are to demystify science. He articulates that the firm has many goals that need to be achieved. Some of them include; keeping people up-to-date with scientific progression, fostering critical thinking, separating sense from nonsense and keeping people out of clutches of impostors. He speaks about the importance of communicating science, adding that there is a huge amount of confusing information roaming around the world. There are many information sources, confusing people on a daily basis.

Dr. Schwarz also added a lot of fun and hilarity to his presentation. The following was one way of showing that humour and at the same time scaring the audience. A person learns that eating fish is good for health as it contains omega 3 fatty acids, which is very good for the human body. The next day the person learns that farmed salmon is contaminated with PCBs. So he leaves the fish and goes to eat French fries. Yet again he learns that French fries contain high amounts of Tran’s fat, which is harmful. Switching his diet to meat, only finding that meat contains Dioxins. Eating buns is not safe either as baking those releases acryl amide, which is an animal carcinogen. Corn contains Lutein, which cannot be consumed either. Then that person learns that corn is genetically modified which makes him panic-stricken. However, there is no evidence that genetically modified substances have harmful effect; that is a concern due to illiteracy. Then the person opts for spinach. He finds out that latest studies show spinach containing E-coli 0157. Even drinking is not safe as just two glasses a day can increase the risk of breast cancer. Then, if a person wants to give up alcohol and drink water, tap water contains chlorine, forming trihalomethanes, which are carcinogens. He then goes to buy a filter, which contains polycarbonates, which lead to bisphenol A. If he gets bottled water, he may intake traces of antimony, behaving like arsenic. Then that person learns that toxins are not just in food items. Deodorants are responsible for breast cancer among females, hair dyes give rise to lymphoma and balloons contain nitrosamines. In conclusion to the whole dilemma, Dr. Schwarcz states that, “If you are hungry, thirsty, smelly, unkempt and bored, you will have a longer life”. : P

Dr. Schwarcz admits that all the above statements are true, but the dosage is not enough to cause the harmful effects. For example, apples contain Acetone and Formaldehyde. However, the traces are very small among the other contents. Carcinogens are everywhere; coffee contains six major carcinogens. Nevertheless, the amount is very low and inadequate to be harmful. Furfural contained in buns, is so little that a person need to eat 6000 buns a day to get enough harmful content. This does not mean low quantities are not harmful. Pituitary gland produces one microgram of hormone per day, which is adequate for the body. Another example is of a toddler who swallowed some beads of a toy and fell sick. The toy contained gamma hydroxy butane in small quantities, which was sufficient for its harmful effect. Even small amounts can be very harmful; but life is full of risks, there by, eliminating one cause with the other.

Hey! There Are Cockroaches in my Chocolate Ice Cream! (Part 2/4)

No, there really are no cockroaches in chocolate ice cream, but as it turns out, Dr. Schwarcz often speaks on the radio and one of his listeners misunderstood a concept about a certain food dye (now a days people would believe anything).

Dr. Schwarcz has some fascinating insight into the public's perception of science. Though not to draw any similarities between him and Carl Saigon but he is also one of those scientists whose most commendable work doesn’t happen in the laboratory but in the public sphere. They distill science to a level where its just right for the consumption by the general populous.

Though unlike Carl Saigon, where the Cosmos was his subject of interest, Dr. Schwarcz has an interest in consumer goods ranging from nutrition, medications and cosmetics to pesticides. His highly visual and entertaining presentation examined some serious as well as some frivolous experiences in dealing with the public perception of these things. The presentation also emphasized the importance of fostering critical thinking.

Sitting in this lecture was more like watching an episode of myth busters, here are a few highlights from the lecture that I found interesting:

1- sales people make a remarkably surprising claim that water filter removes the chemicals from the water and makes it pure and drinkable. For this claim, electrodes were set up in a glass of regular drinking water. Passing electricity turns the water yellow, which was due to the presence of harmful chemicals. However, filtered water formed no residue. To disprove his theory, when common salt was added to the water, the yellow residue was back. The filter removed all the minerals present in the water, reducing its conductivity. The addition of salt helped water conduct electricity to react with the electrode made of iron. The residue formed was simply ferric hydroxide, a good supplement of iron for the body. The water filter did not, by any means, purify the water but it took away the minerals present in it.

2- One of the widely selling products through Internet, the footbath, claims to remove toxins from the body. These toxins are said to be responsible for problems, like arthritis, joint pains, kidney and liver function, circulatory disorder, fatigue and irritability. In veracity, when looking at the real picture, the footbath is following the principle of electrolysis. When plugged in, the colour of water changes to yellow, by ferric hydroxide reaction, due to presence of iron electrodes. The relationship between magic and chemistry was shown by a simple demonstration. An unknown chemical was engaged in a Styrofoam cup as water was added to it. The water solidified to become artificial snow. From this demonstration the presenter wanted to prove that people jump to conclusions before analyzing the facts, representing scientific illiteracy.

3- As mentioned above, Mr. Schwarcz used to come on radio, answering peoples misconceptions regarding science. Once, he received a question on Sodium Tripolyphosphate (STPP). A lady found this chemical in her dishwasher; it was marked as hazardous. She also found the same chemical in Kraft dinner, which was used to feed her son. In order to clear this misunderstanding, Mr. Schwarcz stated that the chemical, Sodium Tripolyphosphate has many tasks. STPP is used in many cleaning agents for better cleaning. In macaroni, it is used to increase water retention capacity. The biggest misconception among people is that chemicals in food are dangerous. The word chemical is mistaken by toxin in many cases.

4- Mr. Schwarcz reports that several advertisements by companies try to fool people through the use of illogical explanations of science. One of the famous commercial is about a type of underwear, claiming to have high absorption capacity. The claim is that the underwear does so, by dissociating the water molecules into hydrogen and oxygen, due to the material of the cloth.

5- Another such illogical advertisement was about Lulu lemon designer clothing showroom. This claims that the clothes are made from seaweeds that release marine amino acids, minerals and vitamins into skin upon contact with moisture. When analysed in a laboratory, no trace of any such amino acids, vitamins and minerals were found.

6- Another example given by Dr. Schwarcz relates to a cosmetic, claiming to be “made by nature, not a chemist”. This statement creates misconception amongst people regarding chemistry. Dr. Schwarcz continuously repeated the statement that all chemicals are not hazardous. Advertising companies often make proclamations without supporting it. One such statement by Lulu lemon states that pops shall be known as the cigarettes of the future. Personally, I agree with the statement. Although the effects of pop are different from cigarettes, the fact that both of them are harmful cannot be ignored.

7- Another extremely ridiculous claim made by a pipes company states that the sudden right angle turn of water molecules, when gushing through straight pipes, changes the bond angle of the water. This change kills water molecules. Therefore, the water we drink and bathe in is actually dead water. The company proclaims that pipes made by that specific company revamps the changed bond angle of water, hence, supplying “pure” water. Although the whole idea is preposterous, the most absurd issue is that people actually claim a positive change in their lives, through the products use. They assert the feelings of betterment after bathing and drinking water from that specific pipe. Dr. Schwarcz Quotes Einstein in conclusion to this example. “Only two things are infinite: universe and human stupidity, and I am not sure about the former.” This quote blew the audience in hysterics.

Hey! There Are Cockroaches in my Chocolate Ice Cream! (Part 1/4)

Its summer and school is over, even though there is still some time before the freshman year at U of T commences, me and my friends have decided to get a leg up on the rest of the class by attending lectures open to public at the St. George campus. I had known about this particular lecture for some time and when finally the day arrived, we all headed out to the venue using the all too convenient TTC.

University of Toronto St. George Campus offers not only one of the best education (if not the best) in Canada but it also has a rich architecture and history, not to mention its ideal location in downtown Toronto, visiting the campus is always fun, even if you are not a student here.

As the weather was dry and the leaves very colorful, the pictures we took actually came out pretty well, which is still a surprise to me. Anyway, in the auditorium we got front row balcony seats. I have always been fascinated with the theater sound system, no matter how you set up a home theater system, technology is still not good enough to miniaturize the grandeur of true theater sound.

Dr. Joseph A. Schwarcz spoke for about an hour and eight minutes on the topic of scientific illiteracy, amongst the general population; presenting well over a hundred slides (phew!).

The Dr. presented with quite a bit of humor, which made the lecture quite interesting (I would say down right entertaining). The lecture hall was pretty full, must have been the unusual title of the lecture. The name might lead one to believe that its something to do with food hygiene but as it turned out it wasn't, I guess people will pay attention if you tell them they have cockroaches in their chocolate ice cream.

To be continued...

finding a walkable neighborhood

its starting to get really hot here, rising mercury doesn't sit well with my already weak resolve for going out for a run around the neighborhood, the gym still seems like a much nicer place to sweat out, fuel at more them $4 a gallon is still not prohibitive for the trip to the gym, at least for those of us who have been crying wolf for sometime and have prepared for this carnage by sticking with fuel efficient vehicle like toyota prius.

Though its uncomfortably hot for a walk out in the sun, one can still enjoy a late evening stroll, but then even that might pose a few problems for those who live in the suburbs.

With memories of San Francisco still fresh in my mind, wouldn't it be great to have more safe and affordable walkable neighborhoods here in northern Virginia, the ones I know off (old Town Alexandria, Reston Town center) are still too expensive for anything even half decent, but then thats just me, there may be many hidden gems scattered around this area which are just that, but since they are more designed to be walkable (one of the things that make a neighborhood more walkable is less traffic) so I might have not come across them during my regular commute (which is often in a vehicle).

Now to address this issue of finding walkable neighborhoods somebody came up with a nice idea for a website (at least the idea is quite appealing), what it does is it gives every neighborhood a score on a scale of 1 to 100, if the area you punch in has a score less then 25 then its not a walkable neighborhood, the 'walkability' rises with the score.

near zero-energy house in northern virginia

its the worst of times for established home builders and the best of times for new and emerging construction companies.

My rational behind that statement? its the worst of times for established home builders as they sit on huge inventories of houses built the conventional way and the only way for them to move that inventory is to slash their prices (and hence their profits), its the best of time for new builders as they can buy land on the cheap and hop on the green building bandwagon. As long as they can deliver a product that is designed with all or some of the zero-energy mantras, they can fetch a premium for it, in many cases even if the house isn't in a desirable school district.

I have been interested in green building and zero energy houses for sometime now, a while back I came across a near zero energy house that has been built in Purcellville, Virginia. Thought about it again when I started looking for green houses (the zero-energy green) in northern Virginia, I didn't find many, Virginia legislature is in dire need to move swiftly on some green energy incentives for home builders, so that we can come shoulder to shoulder with other states that have advanced much further in that area (case in point California).

The house in Purcellville is still one of the very few well documented near zero energy houses even though it was built in 2001, its interesting because the Department of energy has also done a study on this house, you can access this report here.

The other great aspect about this project is the willingness of the owner, Alden Hathaway to share his own experience about the project which he funded himself (so he is under no obligation to share) you can checkout the Family's perspective (who lives in this house) in this youTube footage.


Department of energy finds it a good model though based on the energy usage recorded at the house, the report suggests the household would have been better off with an 8 KW solar system rather then the 6 KW system that they presently have due to their use of computers and other gadgets.

Alden Hathaway has also written a book titled "Building an Affordable Solar Home" you can download the entire book in pdf format here.

fit Fenty

excerpts:

"The Discipline That D.C. Mayor Brings to Cycling, Running Also Marks Politics, Some Say.

Many know that Fenty (D), a triathlete, likes to start his mornings with an early run three times a week. But what's little known are his twice-weekly midday cycling and swimming sessions, reserved by his staff as two-hour blocks of personal time."

"You've got to squeeze it in. If it's a priority, you'll find the time," Fenty said of his workout after he had completed a 33.8-mile course in about 90 minutes. "To be honest, there are times I wish I could be out there longer."

"At 6 feet and 180 pounds, Fenty appears the picture of fit, but he hasn't always been that way. In 2000 -- the year his twin sons were born, he wrapped up a long campaign for a D.C. Council seat, and he and his wife renovated their kitchen -- Fenty did not run a single time. He also reached about 215 pounds, Shawn said."

Dealing With Close-Mindedness

Steve Pavlina is the author of a popular web site and blog dedicated to personal development, you can wiki the author for his bio, here is an interesting post from 2006 about close mindedness:
excerpts:

"How can you intelligently deal with people who are close-minded, totally stubborn in their beliefs and unreceptive to new ideas? Perhaps you feel certain you’re right and they’re wrong, but you can’t seem to convince them to see things your way. And maybe you are in fact right, but that doesn’t prevent the other person from resorting to irrational arguments to keep from agreeing with you. What can you do in such situations?...

...You’ll probably notice that when you get into an argument with a close-minded person, you become more rigid and close-minded yourself, at least temporarily. You might even argue with the other person in your head for days. But the more you develop the ability to compassionately accept people wherever they are, the more open-minded you become. The less you resist, the more you can forgive and accept...

...Being open-minded doesn’t mean being gullible. Being open-minded means that you’re receptive to new ideas and willing to consider other perspectives to see if they hold any value. If they hold no value for you, dump them. If they strike a chord with you, explore them further. The more you can openly consider ideas without resisting the people behind them, the faster you can grow as a human being...."

Tom Wolfe on Mark Twain, Muhammad Ali and Silicon Valley

Interesting words from Tom Wolfe, many will find his commentary on Silicon Valley and its culture of rejecting the ostentatious ways of some other parts of the country (particularly New York and to some extent southern California) quite interesting, according to him there is a difference in the way silicon valley accumulates wealth,he also points out that though during the dotcom debacle Silicon Valley lost the most money, no financial scandal of the size of Enron or Adelphia ever came out of companies based out of this region.

In quoting himself from an article he wrote about Intel-founder Bob Noyce and the birth of Silicon Valley, he mentions how America might benefit by re-embracing Midwestern values such as self-reliance, hard work, discipline and decency. He also shares an anecdote about the Intel founder on how when the man with great ideas built his mansion with an Olympic size swimming pool and three tennis courts he made sure to have thick forestation as part of the property's landscaping not just to protect his privacy but more so that it doesn't become a vulgar display of wealth, he also pointed out that unlike those living on the East coast, where one likes to be driven or flown, the silicon valley culture allows you to buy expensive cars, only if you will drive it yourself, or even keep a company jet only if you will fly it yourself, you can hear all of it here, (Tom Wolfe starts speaking after 8 minutes).

I found this quite interesting as I just got back from San Francisco this morning, I can say that even though the real estate around that region is expensive so much that only millionaires can afford a decent place, I did notice a certain nice way in the attitudes of the locals, it may be due to the great weather, the beautiful scenery all around or just a few right rules of conducting ones life set by the people who first established silicon valley as the technology power house of the country I left San Francisco with a lot of pleasant memories, I think I wouldn't mind returning soon.

Plug-in hybrids a necessity

Plug-in hybrid electric vehicles (PHEVs) are vehicles that not only rely on an engine and an electric motor for motion but whose battery can be charged using an external electric source, these cars can be plugged in to any regular power outlet and charged. right now with existing battery technology there are plug-in that can run solely on electric power for around 100 kilometers (62 miles) per charge; better and longer range vehicles are coming out at a lighting pace, so the future of hybrid looks bright, though none of the mainstream car manufacturers currently produce PHEVs, most of the production is currently from boutique car manufacturers or enthusiast mechanic shops who retro fit your existing Toyota prius with an additional lithium polymer battery pack and some circuitry that works in tandem with out of the box prius power management/distribution system.

Imagine, a person driving every day a distance shorter than the car's electric range would never have to use fossil fuel (you can generate electricity from clean sources such as solar, wind, hydal and to some extent nuclear).

According to EPRI, half the cars in the U.S. are driven 25 miles a day or less. "A plug-in vehicle with even a 20-mile range could reduce petroleum fuel consumption by about 60 percent," says Bob Graham, Manager of EPRI's Electric Transmission program.

its the French

"Everyone is a prisoner of his own experience. No one can eliminate prejudices--just recognize them."
Edward R. Murrow

read this in todays post thought I'd share it on my blog, I would leave it up to the online community to draw there own inferences.

...About 60 to 70 percent of all inmates in the french prison system are Muslim, according to Muslim leaders, sociologists and researchers, though Muslims make up only about 12 percent of the country's population.

...In Britain, 11 percent of prisoners are Muslim in contrast to about 3 percent of all inhabitants, according to the Justice Ministry. Research by the Open Society Institute, an advocacy organization, shows that in the Netherlands 20 percent of adult prisoners and 26 percent of all juvenile offenders are Muslim; the country is about 5.5 percent Muslim. In Belgium, Muslims from Morocco and Turkey make up at least 16 percent of the prison population, compared with 2 percent of the general populace, the research found.

near zero-energy houses in the east coast

there is a new community being built in the east coast that do not require much energy, the pilot project is in paterson, NJ check out the details on BASF website.

The BASF Near-Zero Energy Home-Paterson, N.J., will serve as a proposed template for the City of Paterson's ongoing project to build 3,000 affordable housing units. Paterson is one of New Jersey's largest and most economically challenged cities. Local home construction builders and unskilled labor forces will be encouraged to participate in the project to learn about and implement new energy saving construction techniques into other projects within the region.

Sudoku, the new favorite pass time

Sudoku, which means 'Single Number', seems to be the 'it' mind game these days. Though there's nothing better than doing a crossword puzzle on a nice Sunday afternoon, solving a sudoku puzzle can be just as fun. I have been a huge fan of crossword puzzles and mind games since i was a kid and this craze of sudoku has given me a new challenge to take on. I think a crossword puzzle is a test of one's general knowledge where as sudoku challenges one to use logical thinking and reasoning.

Sudoku was invented in 1979 by an American architect Howard Garns, it became popular in Japan in 1986 and became an international hit in 2004-2005. Howard died of cancer in 1989, and though he lived to see the games success in Japan, he missed its recent Worldwide fame.

Since 2004/2005 sudoku has taken to crowds all over the world. In fact, you'll find that most workplaces now hold weekly or monthly sudoku contests among co-workers. I think mind games like sudoku, tangrams, crossword puzzles, Rubik's cube, etc are all great in developing one's logical, analytical, and intellectual skills. Although such games are usually a hit amongst adults, I think promoting them in the classroom would sharpen a child's skills without using rudimentary ways of teaching.

Like the crossword puzzle, you'll be sure to find sudoku puzzles in almost every electronic or printed newspaper. Here are a couple of resources I use to get my daily dosage of sudoku:

all this will help you

1- improve energy efficiency
2- conserve water
3- improve indoor air quality

If you care for Earth (part 4/5)

when it comes to choosing your diet, look for low-carbon (not just low-carb) diet which means
1- don't condone groceries that have traveled a long distance to end up on your plate
2- choose chicken over beef or lamb
3- cheese is also a high carbon food (same industrialized system, which is fertilizer-intensive)
4- avoid sea food as much as possible ( it requires a lot more energy to keep it fresh and it usually needs to be flown, 80% of seafood in the US market is imported
5- eat locally grown seasonal food
6- avoid bottled water, if necessary then go for locally bottled water
7- order only the food that you will eat (left overs are not good for the planet, as all that energy spent in producing them went to waste plus the food will rot in land fills and create methane
8- do not use paper/plastic plates and cups, use long lasting, durable china and silver ware (use environment friendly dish washing liquid if possible)

If you care for Earth (part 3/5)

Transportation
1- use bicycle
2- use public transport as much as possible whenever given a choice, choose a train, bus (in that order)
3- use an electric hybrid
4- use electric scooters and cars
5- plan your trip before hitting the road so you get more done in single trip
6- ride sharing

If you care for Earth (part 2/5)

Waste management
1- recycle
2- reduce the amount of trash you need to throw out,
3- dont buy stuff that is packed in smaller chunks ( it produces much more waste)
4- ask your home owners association to reduce the garbage collection to once a week instead of twice

If you care for Earth (part 1/5)

if you care about the World you live in and find yourself asking what more can you do to help our planet here are a few tips on how to reduce energy consumption around the house:

1- change all your light bulbs to LEDs or compact florescent
2- buy energy star compliant electronics
3- try never to leave your electronics on stand-by
4- never leave phone charger/adapters plugged in to walls (if you aren't using them)
5- hyper insulate your homes
6- get a higher R rated window pane for your windows
7- use tankless water heaters
8- use detergent that doesn't require a longer wash cycle or hot water
9- use smart washer/dryer
10- avoid central air-conditioning/heating otherwise get multi zone systems, and keep your thermostat at 68 degrees in winters and 74 degrees in summer, use fans
11- do not use microwave
12- get your house equipped with solar or wind power
13- turn off lights when ever leaving a section of your house
13- buy environment friendly detergent, buy hydrogen peroxide instead of chlorine bleach

google web application platform

google recently unvailed its web platform (similar in idea to amazon S3/EC3) you can serve your server side web applications on google scalable infrastructure with free access to google account authentication and google file system, so far only python is supported.

these guys have literally made IT infrastructure business in to a utility business.

Alan Greenspan on fiscal conservatism?

Im just very disappointed, he said glumly, as he sat in his living room. Smaller government, lower spending, lower taxes, less regulation, they had the resources to do it, they had the knowledge to do it, they had the political majorities to do it. And they didnt.

Alan Greenspan expressing his opinion on the Bush administration fiscal policies. I had bookmarked ths interview last year when it first came out, just didnt get a chance to share it, so here it is, still as amusing as it was the first time I saw it.
