Today we are celebrating my 100th post on Share it! Science News. This blog has come a long way since that first post on the discovery of the dinosaur Dreadnoughtus! Thanks for reading and making this possible!
I thought it would be fun to celebrate 100 by taking a look at other "100s" in science!
100 years ago this year, Albert Einstein published his theory of general relativity. The theory, or just "relativity" as it has come to be known in the physics world states: "that all motion must be defined relative to a frame of reference and that space and time are relative rather than absolute concepts". The original general theory deals with gravity, and the second part of the theory, special relativity (that would come later) deals with uniform motion. Recently, the Hubble telescope took some images that provide evidence for Einstein's theory, a nice 100th anniversary present I'd say!
Another anniversary, maybe less famous, yet still influential to science, takes place this year. Pyrex glassware is 100 years old! In 1915 Corning Incorporated introduced a line of borosilicate glassware for use in laboratories. This glassware was low-thermal-expansion, meaning it could handle temperature changes without cracking. This glassware also had many uses in the kitchen and is still used in kitchens and labs today. Now Pyrex sold in the United States is made of tempered glass, but in other parts of the world it is still made of the more expensive borosilicate. I use this glassware at school and at home! You can enter to win some kitchenware at their 100th anniversary website!
In fact, 1915 was a significant year for science in lots of ways. Just to name a few:
- Pluto was photographed for the first time.
- Proxima Centauri, our closest star besides the Sun was discovered.
- The theory of Pangea was published.
- The term "fight or flight" was coined to describe animals response to threats.
- The National Advisory Committee for Aeronautics (the precursor to NASA) was established in the United States.

I'm very excited to make it to 100 posts! Glad you've been along for the ride, here's to more science to share!
