R/unexpected

That actually broke my heart for some reason.

4 minutes of my life, crushed in your hands. 🖕

I died inside for some reason

Dominos show why sound travels faster in solids and slower in gases.

I'll be damned, Domino's is delivering gifs now.

It moves faster because of the number of molecules (density?), but wouldn't that also mean it doesn't travel as far because the energy dissipates quicker?

It’s the right colors and everything.

I don't see the explanation of WHY it travels faster through different mediums.

This is why chaps with massive dongs never fall over.

I got too deep down the rabbit hole for a minute there researching vibration dampeners.

Mfw I'm standing in front of a mirror after a shower.

Creating A Ceramic Zoetrope

Smoke a bowl, watch a bowl.

As awesome as that is, that is too much damn work. Amazing.

Higher frame rate makes the zeotrope more better

Now I need a bowl like this. I'd be watching for hours... with a bowl...

Building a Leonardo da Vinci Bridge

Simplicity is the ultimate sophistication.

Hope that kid topped science that year.

Pretty wholesome to see some father-and-son activities.

If they had used something more sturdy than one inch dowels for the cross beams (and notched the connection points to prevent them from slipping) he probably could have walked on it.  Like here is a full size da Vinci bridge with a floor installed on it.

Simple Method for Drawing Vines on Walls

Simple Method for Drawing Vines on Walls

This is... very specific

Finally I can finish my C64 dungeon crawler

Leaving small gaps of wall instead of just having a solid block of green. It gives a better effect of depth.

I'm having the issue of trying to figure out the difference between the red X and green check mark on the left, they look the same to me?

How sinkholes form through both natural and human-made processes

How sinkholes form through both natural and human-made processes

This phony "experiment" is a cynical attempt to convince the public that it's not the mole people.

This is a great gif, but if someone were to ask me "How do sinkholes form through both natural and human-made processes?", I still would not be able to answer them.

"Well for natural, water gets in the sand and it goes down and collapses. And for man-made, well uh, it's the same thing."

Check out the original video -- I think Grady does a great job explaining it.

Well sinkholes generally happen at or near areas with a large amount of limestone for a reason. Limestone is a sedimentary rock that is easily susceptible to acidic compounds. With increased greenhouse gases filling our atmosphere, we start having problems like ocean acidification or acid rain. This rain trickles down to aquifers underground, and if in an area with large amounts of limestone and acidic rain, we get dissolved limestone since limestone is mostly calcium carbonate(a base) and strongly reacts with the acidic water to create CO2 and water and something else idk I forgot. Water erosion caused by water motion is not the cause. The primary factor of increased rates of sinkholes in the world is the increased acidity of rain in the recent centuries, and the steady dissolution of limestone deposits underground by aquifers that hold said acidic rain. Sorry for the long comment, I tried to cut it down.

Why the camera shutters do this to the planes' propellers

Why the camera shutters do this to the planes' propellers

Wow. Really gives some perspective on how fast they are spinning!

Fun fact: most propeller driven aircraft are limited to 2400-2600 RPM because at those RPMs the tips of the propellers are traveling very close to the speed of sound and at those speeds they lose efficiency and begin to stall.

Sub sonic is easy to manage, supersonic is easy(ish) to manage, but transonic (about Mach 0.9-1.2) is an absolute bitch. Shock waves in the regime tend to be unstable, and that can cause all sorts of mayhem.

You know of Roman Numerals and using hash-marks for counting?

There are a lot of different ways that you can represent numbers, besides the ingrained 0, 1, 2, 3, ..., 8, 9.

The next number is 10, which means 'one ten, and zero singles'. But we could do that with anything! What if our numbers went from 0 to 8, and the next number was written "10" and meant 'one nine, and zero singles'. Then we would have stumbled our way into thinking in 'base 9'.

Taken to its simplest form, we can get rid of all of the symbols for 2, 3, 4... etc, and only use 0 and 1.

We start counting... 0... 1... well, we're out of numbers, so the next number is `10, which means "one two and zero singles".

We keep counting... 11 (one two and one single). Dangit, we're out of room again. Add another digit! `100 (one four, zero twos, zero singles).

...101 (one four, zero twos, one single) ... 110 (one four, one two, zero singles) ... 111 (one four, one two, one single).

If you take the parentheses and convert them back to base ten... 4+2+1 = 7! So base2(111) = base10(7).

base2 is called binary, and its important because it is easy to make electric signals be interpreted as a 0 or 1. It is extremely harder to interpret them as 0, 1, 2, 3, 4... etc.

This wooden contraption is a binary counter.
