Hello, i need your /g/elp. I'm looking
for a logical circuit that follows the table from the image. 'I' stands for Input and 'O' for Output. The 2 botton rows are practically impossible. Thanks to all :D

le particles are le particles but also le waves and exists everywhere and nowhere at same timez

I took some coursework in the subject, but I'm not a physicist. What would you like to know? Explaining everything I know wouldn't be appropriate for a thread.

OP I would have to write multiple textbooks. As I learned QM by reading multiple textbooks.

Can somebody explain Conformal cyclic cosmology to me? My mind is full of fuck.
How can an infinitely expanded universe equal an infinitely compacted one? How does time even exist if an infinite amount of time equals a single instant and how does space even exist if an infinitely inflated universe equals a universe compacted to a single point? How does energy exist if infinite entropy is equal to zero entropy.
I was cool with the idea of a cyclical universe, but I was assuming that a big bang was just a really unlikely vacuum fluctuation that could happen during the infinite amount of time after the heat death of the universe. This explanation however is literally driving me insane.

Basically imagine everything you said there and assign them to dots/discs and you have an idea of what happened before space collapsed into, with about 6 more steps in between that and, time and the big bang
Want me to elaborate?

At t=0, everything is compressed in a singularity, so there is only one single point in space, and it is impossible to reach any others. There is no way to observe any "past" events, but you can still have an effect on future points in space-time - as long as those points can draw their origin to the single point in time and space you're at right now.
At t=infinity, everything is accelerating away from everything else at the speed of light. This means that there is no way to observe or interact with any other past or present point in the universe; no information can ever pass either direction. So there is no way to observe any "past" events, and there is no way to reach any other point in space-time. However, any events that lie in your immediate future, drawing their origin to the single point that makes up the entire observable universe - those you can have a causal effect on.
In other words, in terms of causal connections, how each point in space-time effects each other (or doesn't) and is separated in space-time interval, they're exactly the same in every qualitative sense. You just have to re-scale them. The term for the maps of these causal connections is "conformal surfaces"

Am I the only person here who has nothing to do with STEM in real life? I just like to discuss science and tinker. I dont actually like the professional STEM environment, you have to be so qualified and work so hard for such little pay and recognition and your peers are all insufferable autists.

I think that the extraordinary claim is that life on Earth is somehow special magic pixie dust, and not an emergent characteristic of chemistry and physics, and abundant in the cosmos.

>>7635793
I have seen UFOs with my own two eyes, as have many, many other people. I think it is an extraordinary claim that there is a small branch of humanity which has not just advanced technology but actual science which is decades if not centuries ahead of the reast of humanity, and has done so for the better part of the last century.
>>7635801
True enough. I have seen people actually claim that the ALH84001 announcement was actually falsified and will argue infinitely that there couldn't possibly be fossils from Mars.

How do I subtract 12.12 from 20.00 in my head? I am making it harder than it is.

>>7635730
Subtranct integers first, then substract one more, finally 100-decimals
>>
>>7635730
20 - 12 = 8
100 - 12 = 88
= 8.88
Eventually you learn how to handle it adaptively almost automatically. For example if it was 103.00 - 12.12, you could start with the decimal values first, or just recognize what they would do and just do 102 - 12, the decimal.

>>7635730
>Hmmm subtract 12 from twenty, well there's 8.
>oh shoot, there's a decimal, k, let's just subtract that off the 8 too

I was interviewing with a options trading firm and was asked this question:
>There is an asset whose price goes up 30% with 50% probability
>It goes down 25% with 50% probability
>After thousands of iterations of these prices changes, what is the expected return?
I don't understand...the expected return in a single time frame is positive, but after running simulations on my own, I know that this eventually falls to 0 with many iterations.
Why is this?

50/50, it either goes up or it doesn't

>>7635512
0.75*1.3 = 0.975
>>
>>7635512
Why would this not just be expected value?
(0.5 * 1.3x) + (0.5 * 0.75x) = 1.025x where x is the price of the asset
I'm not very good with stats so I'm not being a smartass. I'm legitimately asking why it wouldn't just be that.
Hey /sci/.
Super Strypi is launching soon, carrying ORS 4 and some cubesats.
The ORS 4 mission is a first flight demonstration of the experimental, low-cost Super Strypi small launch system. The Operationally Responsive Space office is managing development of Super Strypi in partnership with the University of Hawaii, Sandia National Laboratories, the Pacific Missile Range Facility and Aerojet Rocketdyne Corp. The goal is to deliver payloads in the range of 300 kilograms to low Earth orbit. A Super Strypi launch vehicle will deliver the HiakaSat spacecraft and multiple CubeSat payloads into orbit on the ORS 4 mission. Delayed from October 2013, April and October 2014. Delayed from January 2015. Delayed from Oct. 29. [Nov. 2]

Bump because normally /sci/ likes launches
This thing's being launched from Hawaii, and it's basically trying to bring back the sounding rocket concept.

What do you mean "bring back the sounding rocket concept"? Sounding rockets are still a thing. Hard to bring back something that never went away.

OP's pic related is pretty amazing
I personally recommend "How to Build a Habitable Planet" by Langmuir and Broecker, but it's more about planetary geology than astronomy. The first few chapters have some good astronomy shit though. Covers nucleosynthesis, stellar life cycle, accretion, etc.

Your favorite invention? Can be simple or complex. No intellectual posing please.
Pic related, keeping me warm and comfy all winter.
If I had to go higher tech I'd say the internet or maybe our satellite network.
