WHEN: 4-Hour window starting 8:00 AM EST / 13:00 UTC on Saturday, January 18
STREAM: https://www.spacex.com/webcast [https://www.youtube.com/watch?v=mhrkdHshb3E]
Probability of weather delay: 10% [https://www.patrick.af.mil/Portals/14/Weather/L-1%20Forecast%2018%20Jan%20Launch.pdf?ver=2020-01-17-103518-317]
Backup launch date: January 19 & January 20 (Same window)

Launch site: LC-39A, Kennedy Space Center, Florida (East Coast)
Booster number & previous flights: B1046.4 [Bangabandhu 1, Merah Putih, SSO-A]
First stage landing: No—the booster will be destroyed
SpaceX press kit: https://www.spacex.com/sites/spacex/files/in-flight_abort_test_press_kit.pdf
Dragon number & previous flights: C205.1; N/A (Has Mark 3 parachutes)

In-Flight Abort overview:
>For this test, Falcon 9’s ascent trajectory will mimic a Crew Dragon mission to the International Space Station to best match the physical environments the rocket and spacecraft will encounter during a normal ascent. However, SpaceX has configured Crew Dragon to intentionally trigger a launch escape after Max Q, the moment of peak mechanical stress on the rocket.
>After Crew Dragon’s SuperDracos shutdown, the spacecraft will passively coast to apogee, the highest point in its arc. Near apogee, Crew Dragon’s trunk will separate and the smaller Draco thrusters will re-orient the spacecraft for reentry and parachute deploy. When the appropriate conditions are met, Dragon’s drogue and main parachutes will sequence to provide for a soft landing in the Atlantic Ocean near SpaceX Dragon recovery teams.

Brainlets who deny science are shitting up this board and should be banned. The evidence behind mainstream scientific claims is very strong and any threads questioning settled science should be deleted. It's time to discuss real science in peace.
there is no such thing as "settled science", questioning is at the heart of science, anyone who say otherwise are simply afraid that science will one day prove them wrong.

Pfft, thinking that small. No, posthumans can survive atleast for around 10^100 years until the last black hole has evaporated. And by then we might have develloped methods to survive indefinifly thanks to vaccum energy, reversible computing or even escape the end via basement universi. And even then what is simple pleasure compared to the infinity?

It was. For 200 years. Until the last 20. Suspicious much?
>It was. For 200 years. Until the last 20. Suspicious much?

Yes, in a way. It makes me suspicious of the motivations of historical medical officials. This suggests that attitudes towards homosexuality were strongly affected by religious belief, which had lost influence gradually but dramatically over the course of the 1900’s.

I know, I know. I get it. Some 10 % of research has an actual industrial goal in mind. But your super niche chemistry will never be more than self gratification. And don't start with this "you never know maybe one day it will be meaningful to know those things" bullshit. We can foresee a lot of actual worth that a certain scientific finding will have and doing anything else is just jerking your own intellectual cock. I've seen it live. Professors sitting down with their post-docs and tweaking a presentation for some industrial financier to make it look like their fiddling will ever be relevant to the real world. So your "real science" is just as bad as the presumed social science it just happens to be hypocritical about it.
If science was more halal then the middle east would've done something after their golden age 1000 years ago instead of squandering all that time.
Who is this gobbledygook?

Probably doesn't evenhold a bachelor degree.

Things that you think have no application probaby have many useful,beneficial applications and you probably just don't know it yet. Stop thinking with the mind of an everyday consoomer.

Mathematical and biological sciences have their own terminological framework to do logic and proof and foresee things whereas social sciences have always been lacking in basic requirements to be an actual science field.

Indeed,social sciences deal with sentient beings but these sentient beings aren't purely minds or sentience,they also have bodies those are subject to causality, therefore they could have been logicified within a span therefore i can claim that people who work in social sciences are indeed ignorant and unqualified.
Yes, they even tried to inject their obnoxious shit down our throats but failed repeatedly.

>you don’t need to know much more than what is contained in a good applied math program anon
Is there anything I mentioned that wouldn't be in a standard math program or any CS program worth its salt?
>CS is not like mathematical physics in any way
Elaborate on this. I have a strong feeling you, like many before you, are talking about principles of software development and not actual CS. Again, look back on this thread and some of the topics, like domain theory, like complexity theory, etc.. It should be abundantly clear that CS, the mathematical study of computation, is in the vein of mathematical physics. But even in that argument, I'd argue that the problem with so many shit coders and slow dev cycles comes down to that we don't generally expect devs to be trained as rigorously as other engineering disciplines, since the industry wants to pay these people less money. The truth is that the many openings are for literal codemonkey jobs, but the ones they actually need and ought to be paying for are proper software engineering jobs that require more math and experience.

Either way, a lot of industry research positions live and breath on mathematical capabilities.

I have interests in clean energy, electric transport, weapons, AI. A small development here could yield big profits. But I need knowledge for these things so I am asking what I should learn.
basically you need to find a problem, and provide a solution.
design it, apply to start up accelerator (you dont even need the in-depth knowledge - just a solution and a vision)
as long as you can guarantee that your invention works because you can visualise and design realistically then you can borrow from other peoples money and skill pots to bring your idea to fruition
If you want to achieve that level of financial success based on your performance in college then basketball is the topic you want to focus on.
