I just discovered from a tweet sent out by Canada's Science Minister Kirsty Duncan this morning. She tweeted the Top 10 Canadian Science Achievements.

Ken Mitchell, Teacher, LCVI, Lindsay, Ontario on August 7, 2015

I am going to recommend your site as the jumping off point for my students as they research a Canadian Physicist. I enjoyed looking at the profiles and careers of a number of scientists including Werner Israel. I will look forward to visiting often for curriculum reasons and for personal satisfaction. I think the individual layout of the scientist profiles is super! Just the thing to get my students started ... Thank you.

ENC is funded by the United States Department of Education and collects both physical and virtual resources useful to math and science educators. The sites we select for Digital Dozen must have current and accurate math and/or science content. They must support school improvement efforts and have useful multimedia features or helpful navigation.

Elizabeth Yeo, grade 1 teacher, Innerkip, Ontario on September 6, 2013

My students loved hearing from a real scientist! After reading your answer to our question--Why geese fly in a V--out loud in class, I then asked the students for any interesting or difficult words they heard. I only went in depth regarding the concept of lift. We stood in a V formation and talked about what it would feel like to have the wind blowing against us. We also viewed a short video on YouTube about lift and airplanes. They did understand that the bird in front was making it easier for the next one and that it was necessary to be somewhat to the side to get the wingtip uplift. They loved acting it out. Thank you so much!

Mark Elbaz, a student in New York on September 28, 2012

I want to thank you for your assistance, and the service that you provide. If only I could articulate the necessary words. Thank you, and thank you again.

John Bennett, Canadian Polar Commission on June 25, 2012

Thanks for a great website! The information is clear and interesting -- makes it easy to learn about our country's greatest scientists.

francis kunda on May 13, 2012

I enjoy reading from your website.There are alot africa can learn to improve.We in Zambia wish to have this opportunity.

Houcine, a Béchar, en Algereie on January 2, 2012

J'encadre mes enfants pour leurs petites expériences scientifiques, ce site les aide beaucoup dans leurs recherches. Je vous souhaite bonne chance.

Dominic Renaud, Teacher on January 13, 2011

Bravo! I am a science teacher in high school in Terrebonne, QC and I discovered an invaluable source of information on the history and the people who made the history of science in our country. Moreover, everything is available in my language, French. Despite some small error like "cariere" instead of "career", the translation is good and allows us to understand the stories in the vignettes. Thank you for this useful tool in my work in science education.

Judith Anderson, Operation Dialogue, Toronto on December 14, 2010

I love this site. Operation Dialogue is a charity whose mission is to inspire Canadians to think about what it means to be a Canadian. Our Talk About Canada Quiz offers $46,000 worth of scholarships to students. Your site has been one of my favourite sources because it has good information and is bilingual.

Miranda Ying on November 17, 2010

Thank you for clearing this up cuz my buddies and I are doing a science report on oxygen and we wanted to find out who really discovered it. [The answer is in our Ask-A-Scientist Section.]

Popat N Patil , Professor Emeritus, Oregon State U. on August 4, 2010

I enjoyed reading about the life of David Hubel...Thanks!

Craig Loeffelholz of Stillwater, Oklahoma on August 4, 2010

Thank you for the enlightening conversation, and for addressing these/your/our concerns [in Ask-a-Scientist question on aluminum in aluminum lake in cosmetics.]

Andrés Navarrete, a teacher in Santiago de Chile on August 3, 2010

T.S. Eliot's use of a scientific process to illustrate an idea is clever and effective, and it seems more effective to me now thanks to your great explanation. [Check it out in our Ask-A-Scientist section.]

Saima, a 16-year-old student in Calgary on December 16, 2009

Thankyou very much for answering my question. It was very helpful. I appreciate it.

Christian, astronomy enthusiast in Peterborough on November 10, 2009

This has been very educational for me to learn about Einstein's Cross and I really appreciate everyone's time they have spent answering my questions on I feel honoured to have the scientific community entertain my questions like this.

Daniel Duplisea, Research Scientist, Department of Fisheries and Oceans, Canada on January 30, 2009

Great site. Really well organised and informative.

Dan Mazaheri in Pennsylvania on August 21, 2007

Thanks for the information about bee stings. It has been two days of staring at my arm swell, become red, and my fingers begin to feel funny. Wrapped white vinegar around my arm and my arm began to feel better. My fingers weren't feeling funny and now I'm able to make myself a glass of bourbon and diet coke. The combination of smells may be troubling but the result has been nothing but satisfying.

Michele Austin, Industry Researcher, Preston Manning's office on March 28, 2007

We have been looking for a good source for general science information in Canada. Sadly there is no Popular Science equivalent...[but] we have your book and it is a great source. We hope to make science an important agenda item for the government over the next 4 years. Thanks for the book - great source.

doug eneberg on March 20, 2007

Your statistics page did not have the information I was seeking... How many scientists does Canada have? [EDITOR: As of May 2006, which are the latest numbers available, Canada has about 1.2 million people employed in the natural sciences. About 21% are female.]

France Boissonneault on March 20, 2007

All the French pages need to be revised. They are full of errors. [Editor : we are using machine translation for many pages until we can get volunteers or grants to pay for translation of much of the site. If you wish to help out, please email to volunteer or to make a donation. In the meantime, please visit the Major Profiles pages which have been translated by a professional translator.]

Excellent website you have here - I've heard it discussed in several diverse circles.

aditya on June 7, 2006

it was the best website that i had ever visited

Sandie Garrett, Australian student on May 25, 2006

This was very valuble information for my science assignment thankyou very much i love this site you have helped me recieve excellent marks : )

Anas on April 13, 2006

I was wondering how did you establish the Popularity "star-based" mark for each scientists. This popularity thing is at bottom of the left hand tab of each profile. [Editor replies: Thanks for asking. We track the number of unique hits to a scientist's page at We make sure that it's not a returning visit from the same IP address. So the individual's hit counter is only incremented if there is a unique visit from a new person. Of course there is some time limit, so if the same visitor comes back to the site every day, that WOULD increase the hit count artificially. But at least you cannot increase a scientist's hit count by clicking the page refresh button a hundred times. When it comes time to draw the stars, here's how it's done. This all happens in a few milliseconds every time a scientist's page is drawn on screen: 1. The list of all the scientists listed at is sorted in order of hit count, in ascending order. 2. The list is examined to see where the current scientist ranks in that list. So we start at the bottom and say, for example, out of 500 scientists the person is the 200th one. 3. The ratio of the person's rank to the total number is then multiplied by 5 to get the number of stars. So the ratio would be 200/500 = 2/5, if you multiply that times 5 you get 2 stars.]

Patricia Ferguson, Ontario Librarian on March 20, 2006

I'm currently taking a course in electronic information sources through the Southern Ontario Library Service and came across your web site while doing one of the assignments. I must say I am very impressed and will certainly be suggesting to the students that come to me with questions regarding Canadian scientists. We are a relatively small library and don't always have ample print material available for some of the research questions asked. Keep up the great work!

Anonymous, Vancouver, BC on December 24, 2005

Are you accepting new scientists to your listing and if so, how would I get my name added to the list? [Editor: scientists can be nominated by anyone, preferably peers who can provide solid reasons why the individual is truly outstanding in their area of research.]

Felix Blakatu on November 3, 2005

I am highly impressed to view your wonderful achievements in science field. I wish i could become like you people. Please am a young scientist and wolud need your assistance to know more in science field ok? you people have done very enomously.

A.P.Mitra,FRS on October 28, 2005

I was most interested to come across your site. It was most illuminating.

Brett Kessner, Teacher in Australia on October 4, 2005

Thank you for your excellent answers. You have explained it very well and it makes perfect sense.

Tom Gladman on September 26, 2005

I was looking for biographical information on several prominent astronomers in Toronto --Dick Bond, Ray Jayawardhana, Peter Martin-- and didn't find any of them on your list. Hope you will be able to significantly expand your listing soon. [We're working on it, Editor.]

Steve Wagstaffe on June 28, 2005

The quiz is as endlessly facinating as science itself.

Megan Peter on February 20, 2005

Hello, I am wondering if such a comprehensive site exists in French! cheers, Megan

Reyna Jenkyns on January 28, 2005

I think this site provides an excellent resource to Canada's science community. As a recent graduate who is currently unemployed, I don't have the funds to join. However, I was thinking that you should add the Mars Society of Canada to your list of resources.

Thooyaa from Charleston on January 23, 2005

Thanks a lot for your answer [regarding our science fair project]. We really had fun doing this expirement (thanks)--Thooyaa & Amber
