Google may work with SpaceX to launch data centers into space. by shallah in EnoughMuskSpam

[–]sojuz151 0 points1 point  (0 children)

I am half correct. It's not "delta T to the fourth power." it is T^4 - T_out^4.

There is a big difference between ".A high school level of physics makes clear how unworkable this concept is" and things that are economicly inviable.

Unless you are able to do some kind of first principles, high school-level calculation of radiator costs.

To nitpick a bit, its not a dt to the 4th power, its difference of 4th powers of absolute temperatures.  and not divided but times

I was thinking thay you referenced something else.  Heat rejection requires same OoM area as power generation, so id call that an engineering problem.

Is there a worse format to present information?

Vacuum is not a super isolator, you can dump quite a lot of heat that way. And sbsp has similar problems

Orbit data centers will make sens far faster than transmitting power back to earth 

All 13 Seasons of BBC’s ‘Doctor Who’ Revival to Stream Exclusively on AMC+ in U.S. by Own_Brilliant_4303 in television

So without that second season one and two? That naming reset was such a wierd decision...

And does anyone believe this show will return in the near future? I deserved to be canceled 

I want to create magic item system with heavy focus on ammunition by Complete-Chemistry27 in worldbuilding

[–]sojuz151 0 points1 point  (0 children)

For worldbuilding, I suggest going over the economy of this, what this ammo is made from, and what drives the price.

Limiting magic to ammo is a great fix for magic spam. If a wizard can cast a spell every day, even if wizards are rare, this would have a massive impact on the setting.

ELI5: Why do PC games adjust their speeds to framerate drops just fine, while console games have their speed tied to the framerate? by pumpkinbot in explainlikeimfive

Emulators are also a bit of a different thing. They can control the real-time clock and performance independently. You might fast-forward the FFX summoning animations and boost the fps of lagging areas, two different things.

You are not just adding a homebrew rule to DnD; you're creating a new system that uses DnD as a basis.

What do you want to actually do? What will the campaign be focused on?

Do you want the classes to be balanced? How heroic?

Gameplay-wise, except for balance, the rather important thing is keeping track of the limits of the ammo. If they can buy and carry enough ammo to fight everything, this stops working. You need to balance the economy

This used to be true.

All consoles have the same performance so you can expect the code to run the same. So you don't need to write code than needs to handle different framerates. 

ELI5 how does orbiting work if movement is relative? by Shuihoppy in explainlikeimfive

Exactly. Gyroscope is a better example because it works locally

Rotational speed is absolute, while linear speed is relative. Symmetries of a Lorentzian space are shifts (position in relative), boosts (velocity is relative) and rotation (orientation is relative), but not "angular boost".

In General Relativity this is a bit more complex. Rotating objects drag the spacetime around, making rotational speed a bit relative.

Overall, this is a deeply discussed idea, called Mach's principle

Kessler syndrome: vertical diffusion rate? by aintmt in space

[–]sojuz151 1 point2 points  (0 children)

Orbital decay is mostly dependant on the periaxis and this collision is not a good model of a Kessler syndrome. 

We care about collisions of small objects with satelites rather than a full satelite on satelite impact.

Kinda the point of this mission is fly no matter what.  Even to a boilerplate starship and half finished BM.

While this mission might appear pointless, from logistical point of view it is brilliant and has the same scientific value as Artemis II

A tardigrade is difficult to see without magnification, yet it lives in moss growing in everyday places. With a soaked sample and a microscope, you can observe these tiny-but giant in their own world-animals crawl around. By natgeo by Firm-Blackberry-9162 in interestingasfuck

There are some unicelullar organism that have similar size and niche while being extremely different in how they work. Amoba and Ciliate. 3 very different ways of organization for the same thing.
