So Cool! An Online Alternative That Gives Back! Love The "boredom Busters" Section.

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!

This would be funny if it weren't such a PITA

I'm actually getting more pornbot shit than I did before Tumblr banned smut.

How the frick do I block these lovely "followers"?

And another thing...

Why can't we block these lovely followers right from our own Activities screen? Why do I have to go to their page to block them?

Hey, Tumblr! Are you listening?

No?

Are you listening now??

Wow... going to bed now, hope my hubby is still awake.

okay but

fuck your stereotypes

long hair is not “girly”

the same way short hair is not “manly”

hair has no gender

hair is just hair

&as long as you’re not disrespecting a culture with the way you do it

you keep on doing you

This is the best thing I've read all day!!

I used to feed the crows on campus every day because it was easier than making human friends (I had one already - and Robin likes crows as much as I do). Pretty soon, they figured out where I lived and would alight upon my dorm windowsill and watch me. I offered them only healthy things, like leftover fish, hard boiled eggs, nuts, suet, and dog food. They were already habituated to humans and had no fear of us, and I figured it was better to feed them real food instead of the french fries they’d get tossed.

It only got weird when people began to notice that crows would follow me to class. Two in particular would fly alongside me as I walked across campus, landing and cawing for treats and keeping pace with me. Sometimes people would try to scare them off and I’d have to explain that Heinrich and Fatima weren’t bad omens signaling my doom, just spoiled little brats.

Ket...is not that cute, really

Was screwing around with a Chibi Doll Maker and made my Enderal Prophet

Here you should also make yours and reblog with yours attached :D 

You know Alok has got something planned with the grin on his face.

Also found this Doll maker thanks to @syekick-powers​

Power Move is stepping from the back of the elevator, past everyone else, and pushing that <||> button to let that last person on

Hm a lot of you don't seem to know the difference between a "power move" and just being mean for no reason
