>Lockheed compact fusion reactor design about 100 times larger than first plans

Holy shit.
Is fusion finished at this point?
There's literally 0% chance that it will ever be cheaper than fission, let alone other power sources.

I assume the original gag order is still in effect and this is discouraging misinformation.


>http://www.zerohedge.com/news/2016-08-14/shocking-report-finds-us-military-consistently-distorted-suppressed-or-substantially :

CENTCOM leaders "distorted, suppressed, or substantially altered analytic products"

Director of Intelligence and other senior intelligence staff, violated regulations, tradecraft standards, and professional ethics by modifying intelligence assessments

In June 2014, CENTCOM established an around-the-clock intelligence "fusion center"

"Unfortunately, there was no 'fusion' as people whose ideas conflicted with those of senior intelligence officials were not allowed to participate."

In late 2014, senior CENTCOM Intelligence Directorate leaders instructed analysts to cease all external coordination with other IC analysts.

OCTOBER 2014: Lockheed Developing Truck-Sized Nuclear Fusion Reactor

NOTE: This looks to me like they were falsifying reports about my research and excluded me from my own research program, and "in late 2014" after Lockheed went public they had some kind of reaction

>pic related

ANALYSIS: I have previously pointed out how close Lockheed's announcement and related scientific news was to the start of the oil crash. The creation of CENTCOM's "fusion center" in June 2014 aligns perfectly with the crash and it makes sense that the market reacted to the insider information relating to fusion since a successful fusion reactor spells absolute, unequivocal doom for the oil cartel.

17 posts and 2 images submitted.
>>
The triple angle product is in terms of a cubic equation. A number that you can construct with straight edge and compass needs to be the root of some polinomial of degree at most 2. There are some angles which when you get your cubic, the polinomial is irreducible so its in terms of numbers you can't construct with a compass or sttaught edge. That doesn't mean all angles can't be trisected by such means, but it's not true in general. I don't know if there's a purely geometric proof though.
>>
The problem is trisecting the ANGLE, not trisecting a line segment. If you make an equilateral triangle "abc" and then trisect BC with the points X and Y that doesn't mean the angles BAX, XAY, and YAC are the same
>>
>>8876751

AB + AC + BC = 3*radius + 3*radius + 3*radius

AB = 3/1r
AC = 3/1r
BC = 3*1/1r = 3/1r

How is BC not exactly 3/3 of angle A?

If the universe could be defined by a 3D array with each element in the array being the location of elementary particles then the changes in that array over time would be a simulation of the universe?

The problem is where would you store 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 bits of data, since at maximum density it takes the volume of the observable universe to represent that much information? There's no way without compression or simplification. And if you want it to be a simulation you can run, rather than just a recording you can play, you need more data for each point, such as information about its entanglement state.
>>
OP, this is my idea for how to simulate the universe.

First you have to have coordinates for every possible position of a particle. Then you encode the information for where all the particles are, and what type of particle they are etc. The easiest way to store that information is to go into your simulation and put one particle of the appropriate type in each spot in your array where you want the simulation to have a particle of that type.

The best part is that you can use this simulation to predict the real universe, and it's effortless once you do the work of setting it up. Once you get the initial conditions right you can just let it go and it will simulate the universe.

So this is how pi is generated from the lengths of hypotenuses of the form sqrt((1-cos(pi/2^n))^2+(sin(pi/2^n))^2).
Can you please help me understand this better and how this is related to Vieta's formula? And is there a general way to express the nth such nested square root?

Don't you just love how neatly pi is generated by nested square roots of 2? Just as lovely as n/((n!)^1/n) approaching e.
My autistic mind is so satisfied by this.
>>
So sqrt(2+sqrt(2+sqrt(2+...)))=2. So the nested radical expression actually tends to zero on its own but the 2^n makes it just bigger enough for it to approach pi.

Please answer with some quality posts about the subject matter, this is the most interesting thread on the front page after all.

Are online IQ tests reliable? Also, what are the cognitive abilities between different groups of the scale? What separates someone with an IQ of say, 100 from someone with one in the 170+?


Is it fair to assume that you can judge how high or low your IQ is based on whether you are failing or succeeding on your own, self dictated goals in life?

Do you know if it is possible to recover mental capacities lost to really long periods of sustained stress and depression? I used to have a very good episodic memory, capacity to visualize and actual joy from doing so five years back, when I was 17. I am 21 years old now and I've completely lost this, despite exercising regularly, meditating and eating reasonably healthy I have never been able to go back.

If I take something like Adderall I can actually feel a bit like when I was younger, as if being on the drug actually gets me in the same mental state (Memories related to being in that state come flooding back) but it's never exactly the same and Adderall is not really sustainable long term....
Any advice? Should I just kill myself? This is really important to me.

Oh, guy... I am 18 years old. I have nice autobiographical memory, nice memory scientific stuff, nice visualization capacity, facility with languages.
I was always really afraid losing something of that.
But last six months I began to feel like these advantages are mine forever.
Your post scared me.

Stay healthy man, you can definitely lose them. My mind is blank, I don't dream, I hardly find joy in anything, my manic easy going attitude is gone and my short term memory is completely whack, with my episodic memory nowhere to be seen. I think what caused this was prolonged periods of stress, depression, junk food eating and sleep deprivation.


I don't even feel like the same person anymore

The further you reach the further it gets away. At least when it comes to state of mind. I used to suck at pretty much everything math related and had to physically lock my body in place, force my eyes to stay glued to paper and focus.

Eventually you realize that it was literally all in your head. You just have to make the journey to get out of your own way so to speak.

So then, after taking a bunch of psychedelic drugs for an extended period of time (like 8 months) regularly (like once a week), my thought processess and mind aren't like they were before. Not like I can't function anymore, but I can't unthink or unsee some shit I've seen and it's driving me insane. I'm not having literal hallucinations, but the realizations I have had during those trips is haunting me. Is this considered a psychosis?

Can glass soak up moisture?

More precisely, there is a crystal lattic that glass forms. Crystal lattices are structural, in the sense that their net torque is zero. Therefore, water molecules cannot fit in the grooves of the glass molecules because of the torque from the electromagnetic force that the electrons from the glass are expiraling.

There has been extensive research on this matter, however the best is yet to come. Scientists theorize there is a temperature fluctuation within the glass when it is heated to form sand.

>water molecules cannot fit in the grooves of the glass molecules
thanks, i'm glad someone understood what I was getting at. I didn't word it very well
with the bit about temperature fluctuation and lattice structure - if the structure was wider could a glass cup like pic be smooth to the touch but seep water through it like a cloth?
>>
>>8873364
It's possible. The likely option is no, because when you change the lattice you change the idenity of the glass.

Look up helium supercooling on youtube. Helium molecules seep through the container like it's a cloth (similar to your idea) when temperatures approach 0 K
