This describes the distortion that shows up in headlines like this one that seem to indicate that there is scientific evidence against the consensus, when really such evidence is very weak. Really, read that article.

Is Dark Energy real? Who knows; we don't really understand what's going on.

However, is the supernova evidence that the Universe is accelerating wrong? No. What's more, even if it were, you can come to the conclusion that the Universe is accelerating now without even using the supernova evidence, so if you want to show that that's wrong, you have a lot more to do than once again raise questions as to whether cosmic evolution of supernovae could explain Hubble Diagram.

Renewables are undeniably a good idea. The energy is just right there.
Sure they are not without problems, and in a country the size of the UK, there's not enough to be energy independent, but even with that we should build more.

Denying it: Trump - Trump blames renewable energy for rising electricity prices. Experts point elsewhere (and other sources):

Trump called wind and solar power “THE SCAM OF THE CENTURY!” in a social media post and vowed not to approve wind or “farmer destroying Solar” projects. “The days of stupidity are over in the USA!!!” he wrote on his Truth Social site.

So short-sighted... (sigh)

The situation in Tehran is the result of "a perfect storm of climate change and corruption," ...

The current Iranian regime seems pretty "Off with their heads!" for the slightest infraction and they can't punish whatever corruption is at play here? Is it because it's being done by those in religious/political/financial (whatever) power rather than rabble? /s

Thus 5x3 becomes 5x5x5 or 3x3x3x3x3 instead of "STFU and memorize your times tables."

I'm fine with the repeated addition. My objection is the OR in your statement. Apparently not. The question was 5x3 and the kid wrote 5+5+5=15 and got marked wrong with no explanation because the teacher wanted 3+3+3+3+3=15. So I guess that you would have had a 50% chance of being marked wrong on a 2nd grade arithmatic worksheet as well, as absurd as that is. Correct answer notwithstanding.

BTW, that's not at all new. We covered multiplication that way in the 3rd grade back in 1975. Memorizing the table was just to make it quicker. I quickly "discovered" the commutative property while looking at the multiplication table and cut my memorization load in half. The part that confused the father was why is 5x3 = 5+5+5=15 "wrong".

As for 37+55, we decomposed that in the '70s as well, but I soon decided the easier decomposition was 37+55= 87+5 = 90+2=92. So I would say that meme was just someone wanting to complain. Of course the "old way" ends up in 30+50+10+2 anyway.

Shut up and memorize was not in practice during the education of the parents of today's students.

Submission + - Putin's most feared missile downed with a song (telegraph.co.uk)

fahrbot-bot writes: The Telegraph is reporting that Ukraine forces are jamming signals for Russia's ‘invincible’ Kinzhal hyper-sonic missile with a song satirizing Russian propaganda.

Night Watch, the group operating the technology, claims to have brought down 19 Kinzhal missiles – described by Putin as “invincible” – in the past two weeks.

The team told technology website 404 Media that it is using a song and a redirection order to knock the “next-generation” missiles, which carry a 480kg payload and cost around £7.7m each, out of the sky.

Kinzhals and other guided munitions rely on the GLONASS system – Russia’s GPS-style navigation network using satellites – to find their targets. Night Watch developed its own “Lima” jamming system that replaces the missiles’ satellite navigation signals with the Ukrainian song “Our Father is Bandera”.

When the song begins, the Lima system feeds the incoming missiles a false navigation signal, tricking them into believing that they are flying over Lima, in Peru, so that they attempt to change their trajectory. Traveling at a speed of more than 4,000 miles per hour, however, the missiles become destabilized by the abrupt and unexpected change of course.

Night Watch said they developed the system after discovering that the Kinzhals used a controlled reception pattern antenna (CRPA), an antiquated type of technology for resisting, jamming and spoofing. The team told 404: “They had the same type of receivers as old Soviet missiles used to have.

“The airframe cannot withstand the excessive stress and the missile naturally fails. When the Kinzhal tried to quickly change navigation, the fuselage of this missile was unable to handle the speed and, yeah, it was just cut into two parts. The biggest advantage of those missiles, speed, was used against them.”

There is no such thing as anti-hydrogen. You have the anti-proton, with negative charge; and the positron, with neutral charge. The positron will not orbit the anti-proton. You cannot make molecules out of anti-matter.

Wikipedia says otherwise: Antihydrogen.
Antiprotons have a charge of -1e and positrons have a charge of +1e.

... they are recommending software decoding as an alternative to hardware decoding that they took away?

Sounds like they're also recommending people purchase more expensive HW products to get that feature -- or have it enabled. So the answer is - as usual: greed.
