>logic based question

If all current theories require some X item to have always been in existence, and for it to have a progression along the time line from state A to state B (big bang to now for example) would that not, also mean that if X item was always in existence that time, also extends infinitely backwards. With this logic state A would be infinitely backwards on the timeline which would mean that at some point our universe did not have the same laws of time, and or physics. Under this condition all current known theories would be possible on a logical level. (for example matter existed because it was going to exist thus it did. This is illogical in our current state, but plausible in this state.)

Sure. But the very idea that nature operates nonlocally on a microscopic level is profound in itself.

NIH Chief Francis Collins

“I do believe that humans are in a special way individuals and a species with a special relationship to God, and that requires of a great deal of humility about whether we are possessed of enough love and intelligence and wisdom to start manipulating our own species,” he said.
Don't ask my why the fuck he spoke exclusively with buzzfeed about this issue.

Considering the carbons that would normally stabilize the charge are more electron deficient I would say the pKa would go down

What would be the steps to build a smartphone from scratch, including making the tools to mine the raw materials to build the machines that build the machines that build the machines etc. to ultimately make a smartphone?

>>8210213
Please provide a clear definition for "smartphone". Because I can explain how to build a handheld computer with a radio but some of the manufacturing in modern cell phones is incredibly complex.
Why do you want to anyway? Bad NIH syndrome?
>>
>>8210213
>scratch
Fug, since you're including the challenge of mining raw materials the usual
- Buy a Panda Board or Pi
- Buy a TFT
- Buy a LiC-Mg battery, thin form.
- Use plastic or metal or wood to craft case
isn't what you're after.

Process would look like this
- Use a stick you find inna woods to move from Stone Age to the 2nd industrial revolution

The first machine is the blast furnace, stone age Ax, chisel, etc. It's the big one, as you only have a stick to do it.

From there, things get pretty easy-- your primary limit is FUEL, wood is pretty good, but labor intensive, and to make the most out of green wood you either need time, or pyrolysis reduction--charcoal.

Next, you want to take your blast furnace and smelt iron and metalic slag from the earth, You get at least 10 kg of iron per 1000 kg of dirt, so get digging with yoru stone age tools.

Make iron tools, and also use green sand casting to form the basic parts for a lathe.

Since you have no tool steel, re-building your shit lathe into a good lathe will be quite a challenge, but that's the next step.

With your lathe, you can next build a drill press, band saw, etc -and you're at the 2nd industrial revolution.

Amid this you'll also make a dynamo and begin converting heat into electricity, which opens up a host of elements for your utility from the piles of slag from your crust smelting open strip mine where a forest was

the NEXT big hurtle is development of a semiconductor fabricator. This is a chicken-egg problem, as you need robots to make SCs, but you need SCs...

The solution is to employ clockwork as your boot strap.

You'll also need a silica crystal purification unit. These are quite trivial-- but, they require a TERRIFIC amount of energy to run. Hopefully you'll have found a wide coal deposit amid your strip mine

The lithography units, oxydation ovens and so forth are all quite simple machines /once/ you have precision MFG.

Tl;DR: industrial boot strap to semiconductor fabrication.

What real life weapons (that could be carried by a person) could puncture (not shatter or blast) ~4 inches of diamond plating?

Would it be possible for an organic weapon made of earth-like substances (and small enough to be hidden on a normal human sized body) to puncture ~4 inches of diamond plating? i.e. bone spear, wood-like bullet projectile etc..

Also, would it be possible for an organic creature to form a metal utensil that would be as strong as a tempered one? What about a diamond utensil?

In case you're wondering, I was reading some zerg-ish stuff on /tg/ and it got me thinking.

Diamond is heavy and shatters easily with concentrated KE. This is why you only see diamond tools for cutting in CNC machines and the like, and not diamond tanks.
>>
>>8209123
So ~4 inches of steel plating be more resistant then?
>>
>>8209123
What if it was organic material with "the strength" of diamond? That changes it right?

I'm trying to read some papers from 1927, but I'm really struggling with the way Tsiolkovsky presents information here, I think probably just because I am not used to it.

Can someone explain what exactly "f" is here?

Physically or mathematically speaking?

I mean it's some factor, and the answers depends if v is volume or velocity, and how it's related to the length L, or hopefully something of the same unit as it.

Your question is pretty half-assed
>>
>>8208929

I guess whats really throwing me off is how it could be plus or minus the logarithm, and how it could be raised to plus or minus 1.

How come its two things at once, and how do I know which one to use?

Its called an 'ambiguity factor', it was developed by the Spanish mathematician Juan Hernández Valdez.

assuming there are infinite multiple universes there's a pretty good chance that say if you die that there could be another universe where your very same conscience at the time of your death is basically kept alive through some form right?

like people never die completely they just change where they are at at any given time.
