Why is there no 1-methyl pentane?

Posted: 26 Nov 2018 02:46 AM PST

[ive got my answer now thanks guys:)]Can someone explain to me why 1-methyl pentane doesn't exist as a structural isomer of hexane? I've read a few explanations online but I don't understand them. Can you guys help? It's for a piece of work I'm doing on structural isomerism.(Im an a-level chemist who has just started work on isomers and biochemistry)

Would there be caves on other celestial bodies like there are on Earth?

Posted: 25 Nov 2018 07:06 PM PST

It would make sense that Mars would have caves, but would bodies like Europa, Io, Titan or Mercury have them? If so, why?

Apart from humans obviously

Why does alcohol not cause dopamine resistance in the mesolimbic pathway like other drugs?

I know with other drugs, you night end up feeling depressed because you can't achieve the same level of happiness, why does his not occur with alcohol?

How does the cabin in an airplane pressurize and maintain that pressure? Where does the oxygen come from as well?

The mechanics of gravity?

Posted: 25 Nov 2018 10:05 PM PST

Hi there, Science Reddit. I am curious as to how gravity works; is there a formula that links earth's volume and the constant of gravity? Could said formula standardize how strong an object's gravity is? And in the case of earth's gravitational force, what is the distance at which it begins to deteriorate and where it stops functioning altogether, and is there a formula for it as well?

What is assymetric magnetic coupling, and how will it affect our day to day lives if it proves practicable for use in consumer electronics?

Can lasers be focused to reach an arbitrarily large intensity? (Optics)

Posted: 25 Nov 2018 02:03 PM PST

I saw this video on YouTube ( https://youtu.be/jdjTYlReE-I ), where a guy tries to focus a flashlight but cannot focus it to a greater intensity than the source due to conservation of entendue.

In the same video, he then claims he can focus his laser to heat an object to any arbitrarily large temperature, because lasers have negative energy states and can transfer energy to any material with positive energy states.

He shows how he can focus his laser with a magnifying glass to increase the speed of burning on wood.

However, I believe he is wrong. My hypothesis is this: The laser source is actually small, but the beam is widened in a collimator to produce a parallel beam. His magnifying glass merely focuses it back to its original intensity, thus still fulfilling the conservation of entendue.

Anybody know if this is true? Or can you indeed reach positive infinite kelvin with any home laser and proper focusing.

Will a micro or nano scale aerofoil create lift?

Posted: 25 Nov 2018 08:38 PM PST

As long as there is some positive and negative pressure applied to an aerofoil shaped object, will lift always be generated?

Is it possible to calculate how much force/ pressure is needed to make a solid material behave like a liquid/dough?

Will scientists is future will find new elements as we explore our solar system and outer space more? Or every element is already discovered and listed in periodic table?

Why are all the planets of the Solar System revolving on the same horizontal axis but not necessarily every objet of the Solar System. Why aren't all the celestial bodies of the universe on the same plane?

In pills that are designed to be split into halves or thirds: how is it guaranteed that each part contains the same dosage?

Posted: 25 Nov 2018 02:51 PM PST

Say, a pill is designed to be split into thirds and contains 150mg of a specifig drug. How do pharma companies guarantee that each third contains 50mg?

What would the Sentinelese do with their dead?

Posted: 25 Nov 2018 11:50 AM PST

If the Sentinelese have lived on their island for approximately 55,000 years, what would they do with their dead over such a long time period?

I understand we know very little about them, but I'm curious what their after death rituals are such as burning the bodies, or possibly just burying them.
