So, our physics teacher has the strange idea of motivating his students by letting each of us present a physical phenomenal we find interesting to our classmates in a 5-minutes-presentation. And now I need something that is interesting for everyone - even people that usually don't care for physics -, but has interesting facts for someone who's interested in it, too (preferably with an easy experiment). You don't happen to have any ideas, do you?

First of all, your professor is awesome for taking the time to do this. Of the top of my mind, the best one I have is Chladni figures.

Basically take a flat metal plate, fix it at the center and spray some fine sand particles on it.

Using a violin bow, gently excite any edge of the plate to magically witness these beautiful normal mode patterns ( known as Chladni patterns/figures ) forming on the plate.

Also notice that by pinching the plate at different points, the pattern obtained changes.

There is a whole lot of physics that goes behind such a simple phenomenon and I dare say we understand it completely. There are lots of questions on these figures that we have no answer for!

Hope this helps with your presentation. Have a good one!

Hidden Portraits: Nikola Tesla

Nikola Tesla was an inventor, engineer, physicist and futurist. He arrived in the U.S. in 1884 and quickly catapulted his career by working with Thomas Edison, creating more than 700 patents and making major breakthroughs in modern alternating current (AC) electricity.

He’s featured in the Art with Watson series, Hidden Portraits. 15 artists teamed up with Watson to discover and illuminate the unknown essence of seven of history’s greatest thinkers using data. 

What Watson thinks: Watson’s analysis of Tesla’s works revealed a new side of the famed inventor – as an artist at heart.

About the artwork: The Artist Inside was inspired by Tesla’s conflicted, dual personas: the scientist and the artist. The mirrored cube represents Tesla’s mind, with the inner electric grid representing his fame as a well-known scientist. The generative art that come alive inside the cube speaks to Tesla’s lesser-known artistic side, uncovered with Watson.

A short list of realizations from tonight’s photo sorting/editing session:

I have taken a truly astonishing number of photos of hockey players making ridiculous faces.

Over half of these involve tongues. So many that I literally made a Lightroom tag called ‘put that thing back in your mouth’.

Evidence points to the Carolina Hurricanes system requiring players to stick said tongue out when making a shot.

We could probably power Canada with Jeff Skinner’s grin. Someone should get on that.
