Both of you are right, Trumpers are incels and grumpy old folks who feel heard by the troll... opposition are anti-fascists who think protest makes a difference, regardless of age. This isn't primarily an age divide, it's a historical awareness and social empathy divide.

This just in, a report published by a group of people who would be materially harmed by losing business to the EU building its own technical capacity declared it would be costly and unfeasible to ever abandon them.

Two we're considering are the Toyota RAV4 and the Subaru Forester.

May I suggest you consider the Rav4 Prime, which is the plug-in hybrid version? It has enough all-electric range for a daily commute, but several hundred miles of total range. Plus, because it has enough electric power for highway driving, combined with the ICE, it has crazy peak power and a higher towing capacity than a stock Rav4.

What were you saying about market manipulation ??

Indeed. Go read up on the history of the Chicken Tax going back to the 1960s to see a textbook example of tariff protectionism, and part of the reason the US auto market is so damn truck-heavy.

Comment Year 6 of 7 in the Playstation hardware life cycle (Score 1) 71

Of course sales will be slow, they usually are... people are not as willing to buy a console that will soon be out of date. But, on top of that, Playstation (and other console makers) usually drop prices late in the life cycle for this very reason. Because of the AI house of cards, Playstation instead raised prices. To be honest, it's kind of surprising it's merely 25%.

Atomic clocks work using the energy transitions between different electron orbitals. Nuclear clocks work by using energy transitions within the nucleus itself - the difference between the lowest energy arrangement of the protons+neutrons and excited states (isomers).

Normally you need a serious punch to get a nucleus into an excited state: x-rays, gamma rays, or bombardment with energic particles. It so happens that thorium-229 requires the lowest energy to get to an excited state, and that can be achieved with deep-UV (148 nm) light. Laser light at that wavelength has only recently become possible. Also: Th-229 does not really exist in nature, you have to extract it from the decay of U-235, which itself has low natural abundance.

So it's pretty cool stuff, and this first demonstration hints at what could be possible in the future. Atomic clocks use light in the microwave range; this nuclear clock uses light in a frequency band five orders or magnitude higher, and so could theoretically have that much greater precision. And because the fundamental phenomenon occurs in the nucleus rather than the electron cloud, it's much less susceptible to external interference.

Submission + - First Nuclear Clocks Start Ticking in Vienna and Beijing (phys.org)

necro81 writes: Two groups, one in Vienna and one in Beijing, have successfully demonstrated the world's first nuclear clocks. Standard atomic clocks, like the caesium clocks that define the second, operate by observing the transition of electrons between different orbits about the nucleus. The resulting radiation is usually in the microwave range, and can produce clocks accurate to one second in 100 billion years.

Nuclear clocks go a step further, and probe energy transitions within the nucleus itself. Nuclei can arrange their protons and neutrons into different configurations, called isomers. The isomer with the lowest energy is the one usually found; higher-energy ones are only metastable and decay quickly. Usually it takes serious energy — x-rays and gamma rays — to excite a nucleus into a higher-energy arrangement. It so happens that thorium-229 can be excited using UV light with a wavelength of 148 nm — just within the capabilities of some exotic lasers.

It's still been quite a challenge. For one thing, Th-229 is not found in nature; it must be extracted from the decay chain of uranium-235. The Beijing team used just a microgram mixed in a crystal of calcium fluoride.

Although these prototype nuclear clocks are not yet more accurate than existing atomic clocks (one second in millions, rather than billions, of years), they show the way towards what may be possible. Because the energy transition is in the nucleus, rather than the electron cloud, it is less susceptible to outside disturbances like magnetic fields. And the fundamental frequency is much higher (five orders of magnitude), which should yield more precise timing. This development could lead to smaller and more reliable time standards across the world (and solar system).

Just... absolutely staggering energy numbers.!

If you are interested in staggering some more: go check out how much power is channeled via the Gulf Stream, both in terms of heat transport and in shear kinetic energy. It's tens-to-hundreds of terawatts.

(It's tough to tease the Gulf Stream on its own from the larger AMOC, which is on the order of one petawatt.)

...is this fucking legal to withhold federal funding to strong arm states into anti-consumer policies?

Oh wait, it isn't.

Congress itself wrote into the BEAD statute that states must ensure that prospective subgrantees can carry out their projects “in compliance with all applicable Federal, State, and local laws.” And also “Nothing in this subchapter may be construed to authorize” the excutive branch's NTIA to regulate broadband. Trump is abusing a grant agreement to do something Congress explicitly declined to authorize because state laws were already expected to be a part of getting the grant money.

So, as per usual, Trump is just being a bully and making shit up.
