Суперкомпьютер на 2 процессора, 16 ядер за 300-400$ уже реальность!
Опубликовано: 14 мая 2017 г.Ох пусть меня простят маркетологи, продвигающие офигенно новые, но неоправданно дорогие комплектующие для новенького компьютера, но этом видео я вам покажу, что собрать суперкомпьютер для работы можно всего за 300-400 долларов. Все ссылки и рассчеты приведены ниже.
Варианты сборки такого компьютера
1) С таобао (сложно, без гарантий, придется делать переходники, искать посредника, но дешево)
2х 2650 процы + мать + 16Гб ОЗУ = 190$ прибавим + 20 посреднику + 50 доставка (весит оно около 5кг), еще нужен БП с барахолки (15$), видеокарта-заглушка (15$), 80гб винт в целях экономии свинтить у друга, переходники и провода (10$) итого сборка выходит от 300 долларов или около 17 500 рублей
2) С Aliexpress (просто, все кабели стандартные, есть защита Али от мошенников, но дороже)
2х 2650 (80$) +мать (255$) + БП ATX 550W (30$) +16Гб ОЗУ (55$) видеокарта-заглушка (15$), 80гб винт в целях экономии свинтить у друга, переходники и провода (10$) итого сборка выходит от 445 долларов или около 26 000 рублей (Если использовать кешбек, можно получить скидку до 15% на сборке подробности тут — https://cashback.epn.bz/ru/?inviter=8...)
Alcubierre Drive: Warp Speed — Star Trek fantasy or plausible?
Опубликовано: 27 июл. 2019 г.Alcubierre warp drive — faster than light travel? Is Warp speed possible? Enterprise from Star Trek can go 9000 times the speed of light. By comparison, the fastest manmade object, the Juno probe goes 0.0002 times the speed of light. At this rate, it would take 20,000 years to reach the nearest alien planet, which with the Enterprise, would take only 4.5 hours.
But isn’t faster than light travel forbidden by Einstein’s special theory of relativity? There is a loophole. Mexican physicist, and Star Trek fan, Miguel Alcubierre published a paper on “The warp drive”. He manipulated Einstein’s equations of general relativity to make a warp field emerge — regardless of whether other laws of physics would allow it. But his equations are mathematically consistent solutions to Einstein’s equations.
And this is how Alcubierre’s warp drive would work: Take a space ship and put a bubble of space around it. If you can compress space in front of the bubble, and expand space behind the bubble, then you can make the bubble of space along with the space ship, move. This would be like riding a wave on a surfboard. This is where the loophole is in Einstein’s speed limit, that nothing can move faster than the speed of light. This speed limit only applies to objects traveling within space, not the movement of space itself. Space can move at any speed.
So that bubble of space in Alcubierre’s geometric solution can move at any arbitrary speed, theoretically, even 9000 times the speed of light. But Can space really move at faster than light speed? Yes.
Space is being expanded in the back of our spaceship, and being contracted in front of it. Can space expand and contract like this? Yes, Space is allowed to do both. Space is contracting around you and earth right now. That’s what gravity is. Similarly, Space can expand too. It is expanding right now on a cosmological scale.
Alcubeirre’s warp drive, creates a bubble around the ship, which is like the surfboard. The ship sits within this bubble. Your ship does not move within the bubble itself, so Einstein’s laws are not violated. To make space warp locally around a spaceship like this requires a lot of mass or it’s Energy equivalent via E=MC^2. And this is not just regular mass or regular energy. This is negative mass and negative energy.
How do you get anti-gravity? You need negative matter – or exotic matter. This is something that would have negative gravity. The problem is Negative matter is not known to exist. Note that negative matter is not anti-matter. Antimatter does not have negative gravity. It has positive gravity. You could substitute the energy equivalent of negative matter, and that is negative Energy. But again, what the heck is negative energy? This is not the same as an absence of energy. It is energy with a value less than 0 that would allow you to expand space-time. But Antigravity has never been seen in a lab.
However, anti gravity, negative mass, and negative energy are not forbidden in Einstein’s equations. Could this mean that if we are clever enough, could we create it? Let’s presume that we could. There is group at NASA called the Advanced Propulsion Team, also known as Eagleworks, who is working with this assumption. Harold White’s calculations show that a 10 meter diameter ship could go at 10 times the speed of light.
White’s team has even tested the feasibility of warping space by doing a very small scale table top test. They have attempted to slightly warp the trajectory of a photon, changing the distance it travels over a fixed length. The first test was done in 2013 and was inconclusive.
Is negative energy even realistic? What about the Casimir effect displaying negative energy? This is a quantum mechanical phenomenon that occurs when two conducting plates are brought very close together. When this is done, a certain proportion of the virtual particle frequencies between the plates are excluded, because not all frequencies will fit between the 10 nm space.
Frequencies with wavelengths higher than 10 nanometers will be excluded, whereas, all frequencies will fit outside the plates. The pressure outside the plates is greater than the pressure inside the plates. This creates is a real mechanical energy that can be measured.
Some scientists have proposed harnessing this negative energy of the vacuum on a large scale. But this is flawed, because the energy between the plates is not negative. No energy be harnessed to make a warp drive using the Casimir effect?
There is one observational phenomenon that should give us hope that negative energy or anti gravity may exist. 70% of our universe is made of this. It is expanding space. It is possible that sometime in the future, if we can develop a better understanding of dark energy, we can learn to harness it, and use it to power the warp engine.

--------------------
This week i assembled the most gorgeous machined Aluminium Bearing Housings Made by Alexcnc from the MMX Team.
They are adjustable for the Depthing of the gears. We are also implementing the new PBS — Product Breakdown System for the Whole MMX. Chris, the new project manager has introduced me to the sacred lands of Excel heaven and although there is a lot of initial work we have to do to make this function properly, the long term efficiency will improve a lot! We are taking the MMX from being a one off DIY maker project to being a scalable, fully fledged — ready to build for any competent group of people — machine. Its really great!
If you want to SUPPORT US:
The fact that you are watching the videos and care about the music and future of Wintergatan is the best support anyone can have, I want to thank everyone who is here for that kind of support, it is really the fuel for the Wintergatan Engine.
If you apart from that further want to support the projects, we have these different options set up:
YOUTUBE MEMBERSHIP
►Support by Joining the Wintergatan Youtube Channel by clicking the blue JOIN button next to subscribe or go here: https://www.youtube.com/user/winterga...
As a Member you'll have a Wintergatan badge next to your comment, long term members receive guest list tickets and early access to ticket sales for the upcoming world tour.
Why do we accept support in this way?
I, Martin, can already sustain myself 100% doing what I love to do. If you want to support artists/organisations who have not yet reached that privileged position, please consider supporting other artists/organisations who need the support more. With that said, I have too many ideas and too little time and with your support I can get more help from people around me to execute the ideas better and bring them out in the world faster.
