I am impressed by the level of systematic complicity some men and society have when it comes to women. Like men can be completely predatory, and still victimize themselves and try to frame those who call out their behaviour.

At CES, NVIDIA, AMD, and others spoke about using AI to accelerate nuclear fusion.
The deeper question:
are we building a tool to stabilize civilization—or a system that consumes the very energy and order it depends on? https://t.co/s3VPB2kh4z

@ItsJustVV weren't they testing the different recommended cpu settings dud to the intel crashing issues with their cpus?

@YourMomDave1 @ihaveabluehat @elonmusk They're not competitive from a cost perspective

[F. Perez @Perez_MFernando]

@YourMomDave1 @ihaveabluehat @elonmusk So you have a career agaisnt time, you either invest to protect for future at the expense of economics or wait until the technology matures and risk destroying the future.

[F. Perez @Perez_MFernando]

@YourMomDave1 @ihaveabluehat @elonmusk Consequently, there efficiency is relatively high. "Green" technologies are potentially more efficient but you need energy carriers, the steps needed reduce potential efficiency. Thus, further developments are necessary to have an economic edge.

[F. Perez @Perez_MFernando]

@YourMomDave1 @ihaveabluehat @elonmusk Technology has to have subsidies to be adopted. The tax can't be a communism, it would really be a discount, the rich have to pay the tax for there to be proportionality that allows adoption. Probably why he doesn't calls it communism now that he profited from the adoption ordeal

@handsomesafi @9550pro My 7950x scores about 35-36k when at 125W so about the same. In the other next lower power limit it does about 31-32 but I can't remember well this bit. In stocks it goes slightly above 38k. I've never turned on so the OC but I have mostly used it at 170W because my workloads.

@MrBeast Man some people would do it for free? why don't you pick up some homeless for the experiment ?

[F. Perez @Perez_MFernando]

@Buildzoid1 For some reason I found this extremely entertaining.

[F. Perez @Perez_MFernando]

@BSeradjeh @ScienceWDrDoug @Andercot I thought it could be possible to estimate the properties of this sample, but I have no idea of it's density/volume/weight and the strength of the magnet below. Hence why I find all this so dodgy, a couple details could help to know what is actually is but...

[F. Perez @Perez_MFernando]

@BSeradjeh @ScienceWDrDoug @Andercot This depends on the rise rate of the applied field, whether there's relaxation time for flux lines to reposition and whether the applied force overcomes the pinning force. It's a bit hard to guess what this is or it's properties with a video.

[F. Perez @Perez_MFernando]

@pferg42 @Andercot The data presented seems to avoid measurements that are fundamental and common in publications of this type and when presented, they are not very practical for proper interpretation.

[F. Perez @Perez_MFernando]

@pferg42 @Andercot For example, if they made this material and considering its quite small, I see no reason they don't place it in SQUID to see its magnetization/current,etc. It would take them a couple hours. The data presented so far seems cherry picked.

[F. Perez @Perez_MFernando]

@pferg42 @Andercot Unfortunately, I myself do not have the possibility or equipment to try to fabricate such material. I am taking a break. However, there seem to be many red flags, they don't necessarily imply this can't be real but they at least make this research look very dodgy.

[F. Perez @Perez_MFernando]

@pferg42 @Andercot This possiblity irrelevant the argument that @Andercot says of the LK99 having poor interconnection between the SC states. Easiest way it's to just assume the material has a defined shape, it won't be the answer but it would be a decent approximation, all depending on the data.

[F. Perez @Perez_MFernando]

@pferg42 @Andercot my comment is regarding to the fact that if they have mixed state then it is possible to measure the magnetization. Doing measurements using a 2D grid, or better yet in 3D, it is possible to reverse calculate the current density.

[F. Perez @Perez_MFernando]

@Andercot I think this could work for particular research topics, in the case of SC the community is relatively small compared to other sciences.

[F. Perez @Perez_MFernando]

@almarakby_amr @bostrom_adrian @ScienceWDrDoug @Andercot I disagree. A video just shows it is levitating. The needed proof is the mechanism, a video would be worthless if there were miniature hamsters running a fan to hover it. Measurements can tell why things happen.
