What the Hell? This is so cool! Wish my physics teacher had done cool stuff like this

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!

My local library has a "Thingery" section with all kinds of things you can borrow... sewing machines, drones, skates, GPS units, kayaks, video recorders, laptops, telescopes... So many things to try! Libraries have reinvented themselves in the most interesting ways.

Today I learned

OMG the picture... I loved the text when it came out so long ago, but the picture just makes it amazing! (Nice watercolor work, too!)

there seems to be a mysterious woman laying down on the sand and enjoying this with them. proph recognizes her and just leaves her be, as she, too, is in need of a little break.

1.) Denial

just learned that magnolias are so old that they’re pollinated by beetles because they existed before bees

jespar: hey, you okay?

prophet: what is…okay?

jespar: maybe get some rest?

prophet: my resting heart rate registers as a…

prophet: panic attack.

ignoring ur academic responsibilities is all fun and games until ur behind on 30 readings and have 6 things due in 4 days

That was fun!

Mutuals are tagged to do this picrew if they so desire~

Nice! So, what were your awesome meals? Did you know that pictures of meals are nearly as common on Facebook as selfies?

So today was much more eventful, as illustrated by the pictures below, including my first-ever selfie! The day started off with me discovering that my biological clock set itself, as I woke up 6:00 am, local time. Following an absolutely superb breakfast and finding an imperial system of ants...
