Given that you can always half a number how come two bodies touch but the distance between can also be halved?

Answer 1

Two bodies never actually touch.

What we perceive as touch is actually the electromagnetic (EM) force of the surface electrons repelling each other.

Some quantum physicists have even theorized that at the subatomic layer, space is not even continuous like a number line; instead particles have to blink in and out in order to move through otherwise consecutive locations in space.

Personally, that's too weird to think it's true, but I like where the idea takes my imagination... :)

As for halving the distance, you'll probably enjoy looking up Xeno's/Zeno's Paradox.

Answer 2

Semi R's have been given it lined from the mathematical element, so i'm going to take the physics element. once you get all the way down to the atomic scale, the entire theory of place alterations dramatically. Electrons don't have a single place. truly, they exist as a sort of cloud of danger. while measured, the electron will snap to a single area, even yet it rapidly spreads out back, so the subsequent time you degree it, it is going to likely be in a distinctive place. The danger cloud extends to infinity, so there is an danger (however pretty small) that the electron would be got here upon midway around the room once you degree it. So, measuring the gap between issues works nice on a macroscopic scale, yet measuring the gap between single debris is a fuzzier theory. the main suitable you're able to do is to establish the main in all probability distance between issues, with the aid of fact it is going to alter every time.

Answer 3

That's like asking how you can count backward from one to zero given the infinite number of real numbers between one and zero.

If you took the same amount of time to close each 'half distance', they wouldn't touch. But thats not the case, your fingers close each 'half' in half the time - give or take.

Any distance moved can be subdivided into an arbitrarily large number of smaller intervals. (down to the quantum level).

Answer 4

When the distance is 0, half of it is also 0.

Answer 5

1.618(the number PHI).Pronounced as 'fee'.This number is very important in art because as many experts say,it is preety.It is considered the most beautiful number in the universe.

The number PHI was derived from the Fibonacci sequence-a progression famous not only because the sum of adjacent terms equaled the next term,but because the quotients of adjacent terms possessed the astonishing property of approaching the number 1.618-PHI

Despite PHI 's seemingly mystical mathematical origins,the mind boggling aspect of PHI was its role as a fundamental building block in nature.Plants,animals and even human beings possessed dimensional properties that adhered with eerie exactitude to the ratio of PHI to 1.The early scientist heralded 1.618 as the divine proportion.

The female bees always out-numberedthe male bees and if we divide the number of feale bees with the number of the male in every beehives in the world you get the same number and that is the number PHI-1.618

Sunflower seeds grow in opposing spirals.The ratio of each rotation's diameter to the next is PHI-1.618

Human bodies are made of building blocks whose proportional ratios always equalto PHI.Take the distance from the tip of your head to the floor and then divide that to the distance of your belly button to the foor.You get PHI.

Want another example?Divide the distance from your shoulder to your fingertips to the distance of your elbow to the fingertips.PHI again.

Another?Hip to floor divided by knee to floor.You get PHI again.Finger joints.Toes.Spinal divisions.PHI.PHI.PHI.

So the answer to your question is the divine proportion.I hope i get it right.Don't quite get your question actually but this is what
my fiance says is the answer.He's a DNA analysis so i hope that is what you are looking for.

Answer 6

Doh! Watch list.

Answer 7

Because numbers are not physical entities, but only concepts.

Answer 8

do you really think that this type of question will come up on a day to day basis when you get out of college?
