Mr. Dael's World of Mathematics is a place where students and parents can get information about his mathematics classes at Alexander High School. It is also a place to find out interesting facts about mathematics.
This is a really interesting animation about water.
Every day you drink dinosaur pee.
This is the weird world of water…
sciencealert.com A series of new animations by a NASA scientist show just how zippy – and also how torturously slow – the speed of light can be.

I like this.
Too bad we were not in school today.
Happy e day! In celebration of Euler's number, today, 2/7/18, is known as e day. How will you celebrate?
This is a very attractive question.
sciencedaily.com A collaborative computer project has discovered the largest known prime number. The new prime number is nearly one million digits larger than the previous record prime number, in a special class of extremely rare prime numbers known as Mersenne primes.
Every physics student at Alexander HS should be able to answer this question.

This is really cool.
Robert Lang is a physicist who worked at NASA studying lasers and has 46 patents on optoelectronics to his name. However, that's not what he's best known for now: he's a legend in the world of origami. His intricate designs are second to none, and they actually have applications back in engineering.

Vivid glowing auroras in Jupiter’s atmosphere! Our Hubble Space Telescope spotted this stunning light show. This observation program is supported by measurements made by our Juno spacecraft, which arrives at Jupiter on Monday. While Hubble is observing and measuring the auroras on Jupiter, Juno is measuring the properties of the solar wind itself; a perfect collaboration between a telescope and a space probe.

Auroras are created when high-energy particles enter a planet’s atmosphere near its magnetic poles and collide with atoms of gas.

One of the tragedies of mathematics.
telegraph.co.uk/news/science/8… Scientists said on Thursday they recorded particles travelling faster than light - a finding that could overturn one of Einstein's fundamental laws of the universe.
Interesting Science and Fiction.
This is a good warmup for the 2nd semester.
sciencedump.com Can a YouTuber explain something as complicated as General Relativity better than your physics professor? You may not think so, but watching this guy get launched from his car seat, sending popcorn flying all over the inside of the car – all in the name of science – makes a pretty convincing case if…
