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!

Wow! Eye-opener! Honestly, I never understood why people don't do this...It seems so logical to me.

I no longer struggle with math, though...once you realize it's just a language that describes the world around us, the veil is lifted and tossed to the wind.

finding out people dont usually add numbers by first adding something to make a ten (for example 7+6= 7 plus 3 is 10 plus another 3 is 13) & that its actually an adhd thing is the WILDEST shit literally ive lived like 10 years (or however old i was when i learned to add and stuff) thinking thats how everyone does it. what the fuck

We are in an area loaded with rivers, so my parents would have had their pick of:

Menomonee, Kinnickinnick, Milwaukee, or the tributaries Honey or Root. I'd go with Root, personally.

The other day I learned on Twitter about a girl that was nearlly named after the river on her town. So, reblog with what your name would be if it was based on the river on your town (or the closest river)

Would wait in long lines to ride this !

so anyway, here’s this surprisingly paleontologically current carousel deinonychus

For your Friday, I give you a frog in a dish garden.

Somewhat nervously awaiting 2018...

If 2017 had a title it would be, ‘And you thought 2016 was bad’.

Wow... so true.

What if you kept a chainsaw in your bedroom instead of a gun? Imagine the fear that would enter an intruders mind hearing that?

It’s hard to tell if someone likes you when you don’t even like yourself.

Gotta keep moving or the other part will catch me...

High-functioning anxiety sounds like…

You’re not good enough. You’re a bad friend. You’re not good at your job. You’re wasting time. You’re a waste of time. Your boyfriend doesn’t love you. You’re so needy. What are you doing with yourself? Why would you say that? What if they hate it? Why can’t you have your shit together? You’re going to get anxious and because you’re going to get anxious, you’re going to mess everything up. You’re a fraud. Just good at faking it. You’re letting everybody down. No one here likes you.

All the while, it appears perfectly calm.

It’s always looking for the next outlet, something to channel the never-ending energy. Writing. Running. List-making. Mindless tasks (whatever keeps you busy). Doing jumping jacks in the kitchen. Dancing in the living room, pretending it’s for fun, when really it’s a choreographed routine of desperation, trying to tire out the thoughts stuck in your head.
