Where were you when you realised Elon Musk's idea is a pipe dream with no real contingency?

I'd rather that than risk staying on one planet until an extinction level event we cannot surpass eradicates us. I had children to preserve my genetic legacy and will go to any length to ensure the longevity of organisms that are my progeny.

Has anyone on /sci/ ever experienced a phenomenon known as "The Hum," or have thoughts on the cause of this phenomenon?
https://en.wikipedia.org/wiki/Talk:The_Hum
https://hummap.wordpress.com/
Several months ago, I started hearing a somewhat faint rumbling sound that I couldn't localize. It's like a bulldozer idling in the distance. The sound contracts rhythmically, like a pulse. There's the faint idling bulldozer sound for a second, then a second of silence, then the bulldozer sound again, etc.
The sound occurs sporadically at different times of the day. Some days, it could start as early as 10 AM, but it usually begins around the afternoon. The sound drones on until 1 AM or 3 AM, then it seems to cease for the rest of the AM hours. The sound endures for several weeks, sometimes a couple of months. Then it ceases entirely for several more weeks before starting up again.
The sound is worse indoors than outdoors. While indoors, the sound becomes a more intense rumbling. Earplugs and earmuffs do nothing to block it - the sound rumbles through them. White noise generators and music do help to drown out the sound. Plugging my ears with my fingers also curiously helps, if only because this produces some kind of pulsing that drowns out the sound.
Some people I've asked can also hear the sound, but some others can't.
I've made several efforts to locate the sound. At first I honestly thought there was some sort of construction occurring on a neighbor's lot, but I haven't seen any construction vehicles anywhere in the vicinity. I also used Google Maps to check dozens of square miles around my neighborhood. There's no construction, no factories, nothing that could explain this disturbance.
Driving some distance away from my neighborhood causes the sound to cease, but I can't get a more precise idea of where exactly it begins or ends.

How are organizations communicating with satellites?
It's stated that the transmissions are radio waves, don't the majority of them reflect off the Earth's ionosphere?

Depends on the frequency.
>>
>>8479087
But wikipedia tells me that the ionosphere is from 50 to 1000 kilometers up.
Then they say that satellites can range anywhere from 700 to 30,000 kilometers up.

I have a question for you Sci. I have amassed an Excel Spreadsheet containing about a thousand linear functions that I need to calculate the integrals of. I'm not about about to sit here and punch a thousand functions into a calculator by hand, so my question to you is: how would I go about automating this task?

My son's biology teacher believes that vaccines cause autism. I have talked to the teacher multiple times but he is too stubborn to listen to any outside opinions and only delves in a few vague articles supporting his view. Would any of you know of concrete evidence to support my case?

How would a universe with two time dimensions behave?
24 Posts / 2 Images
View this topic
>>
Like cell division
Every planck unit the universe(s) would split into 2 parallel universes
>>
Infinite timelines running parallel to each other horizontally. Everyone has a decision to make at every unit of time and making certain decisions pushes you down a different timeline. People literally watch others jump into and out of the timeline they are currently in in real time based on the decisions a person makes. Increasing slopes (decisions) hops you into more and more positive timelines. Decreasing slopes hops you into more and more negative timelines. Positive and negative don't necessarily mean good or bad, it's just a direction.
So imagine it's like a bunch of streets running parallel to each other with a bunch of intersections.

Where should I go if I want to patent a mathematical proof?
I want to have the exclusive right to use my proven theorem. If any other mathematician needs to use it in his proof, he either has to pay me, or his proof is to be considered invalid.

Why not redistribute the work amongst the non-mathematicians?

You can't, as it's not your invention. It's just a discovery of a naturally occurring Phenomena.
You can't patent ideas.

Because they were cost plus contractors who would only do what NASA tells them to & also pays them to
SpaceX however is optimizing for costs from their end

Without reusability and modern materials it would cost too much.

Psychology is harmful alchemy and shamanism. Why dont we banish it from science and stop financing this esoteric field? Neuroscience and psychiatry should absorb psychology. Its useless major for people who dont have social skills so they can be more efficient at mcdonalds.

psychology uses quantitative methods

It's just not a hard science you cock lord
If we should banish anything it would be sociology, psychology actually has some uses outside of targeted advertisement
>>
>>8478685
Their reliability and validity is too low to be useful. Also they use qualitative research heavily.
>>8478686
Sociology actually has more reliability than psychology because they dont care about individual psyche. Psychology is just intuition with very very soft research so you are like 5-10% more right than regular layman. Its shit and there is no significance. No math and no anything. Its just a branch of philosophy.

The social sciences, manipulation of the masses, marketing, and energy economics. You an take computer science if you want to twiddle around with simulated CO2 molecules on super computers all day for the UN but those are dream jobs and hard to land. You might need to get knee pads.

That's a decent book. Depending on what level you're at, you could start with introductory geoscience books like The Earth System (Kump, Kasting, & Crane). If you're going deeper, you might want things like Atmospheric Thermodynamics by Bohren. There's a lot of science that goes into climate change, so you could really study almost anything and it would play a role.

Why should we? Linear algebra and multivariate calculus gets you through everything, except complexity theory and cryptography.

Who needs math when we have computers to do the math?

How the fuck did most CS students know what that was? You learn it in first year in any European university. Holy shit America sucks.
