fusion is extremely difficult
dennis whyte is covers it about as well as anyone
there are several yt videos with him out there
this one has a breakdown/time stamps in the show notes that will allow you to see/hear what you want
enjoy

PALMDALE, Calif., Oct. 15, 2014 – The Lockheed Martin Skunk Works® team is working on a new compact fusion reactor (CFR) that can be developed and deployed in as little as ten years. Currently, there are several patents pending that cover their approach.

The New Yorker has a piece about the degree to which new weight loss drugs are having an impact on the culture and the economy.
An excerpt:
"The science of GLP-1 agonists has often zigged, and now it might zag. GLP-1 produces all sorts of cascading effects; the human body has receptors for it not only in the gut but also in the liver, muscles, and brain. Studies keep turning up surprises: some of the medications appear to reduce the incidence of heart attacks and strokes, slow the progression of kidney disease, and shrink dangerous fat deposits in the liver. People who take them have reported diminished cravings for alcohol and tobacco; some have reported feeling less compelled to gamble, compulsively pick at their skin, and engage in other addictive behaviors."
And, the story suggests, we're still discovering the impact that these drugs will have on on a country where obesity is seen not just as a national health problem, but also a national security issue.
Will they grow back just as crooked and rotten as my first set?
I hope not. All the while, my teeth..... Harold Bluetooth (á¼á á±á ááᱠᬠá´á¢á¾á¢á´á¦)'s teeth mustabin Colgate in comparison, I guess.
If sound is vibrations, then the falling tree certainly does make a sound, because it produces vibrations in the air. Even if thereâs no person or other animal around to hear the sound, a recorder with a microphone could certainly record those vibrationsâas sound.But wait! Remember in the first paragraph I said that thereâs more than one definition of sound? Another definition is that sound is the sensation we experience when our ears detect those vibrations and send information about those vibrations to the brain. In other words, by this second definition, sound is what we hear, i.e., the perception in our brains
In the "Transcendental Aesthetic" section of the Critique of Pure Reason, Kant outlines how space and time are pure forms of human intuition contributed by our own faculty of sensibility. Space and time do not have an existence "outside" of us, but are the "subjective" forms of our sensibility and hence the necessary a priori conditions under which the objects we encounter in our experience can appear to us at all. Kant describes time and space as "empirically real" but transcendentally ideal.
Kant was wrong: time exists outside of humans and can be measured without the existence of humans. However it takes humans to associate the passage of time with its presence in space and effect on objects.
Interesting story on why does time move forward, and why did the universe start (big bang) from a low point of entropy.
The arrow of time began its journey at the Big Bang, and when the Universe eventually dies there will be no more future and no past. In the meantime, what is it that drives time ever onward?
When Isaac Newton published his famous Principia in 1687, his three elegant laws of motion solved a lot of problems. Without them, we couldn't have landed people on the Moon 282 years later. But these laws brought to physics a new problem, which wasn't fully appreciated until centuries after Newton and still nags at cosmologists today.
The issue is that Newton's laws work about twice as well as we might expect them to. They describe the world we move through every day â the world of people, the hands that move around a clock and even the apocryphal fall of certain apples â but they also account perfectly well for a world in which people walk backwards, clocks tick back afternoon to morning, and fruit soars up from the ground to its tree-branch.
How does a clear direction of time emerge from these descriptions of the Universe, which all lack their own arrow of time? As Marina Cortês, an astrophysicist at the University of Lisbon, puts it: "There's a lot of implications that start with taking seriously the question, 'Why does time pass?'"

As if this wasn’t terrifying enough, Swan’s research finds that these chemicals aren’t just dramatically reducing semen quality, they are also shrinking penis size and volume of the testes. This is nothing short of a full-scale emergency for humanity.
