Moon Hammer and Feather Drop
In 1971, during the Apollo 15 mission, astronaut David Scott conducted a famous science experiment on the Moon’s surface. He simultaneously dropped a hammer and a feather from the same height, demonstrating the concept of gravity and air resistance.

The Experiment
On August 2, 1971, Commander David Scott, a former Air Force pilot, performed the experiment at the end of the last Extravehicular Activity (EVA) of the Apollo 15 mission. He held out a 1.32 kg aluminum geological hammer and a falcon feather, releasing them from approximately 1.6 meters above the lunar surface. The objects fell to the ground without any air resistance, allowing them to demonstrate the same acceleration due to gravity.

Results
The hammer and feather fell at the same rate, striking the lunar surface simultaneously. This experiment confirmed Galileo’s centuries-old theory that, in the absence of air resistance, all objects fall at the same rate regardless of mass. The Moon’s gravity, which is one-sixth of Earth’s, also played a crucial role in the experiment.

Significance
David Scott’s moon feather and hammer drop experiment was a groundbreaking demonstration of scientific principles in a unique environment. It showcased the validity of Galileo’s theory and highlighted the importance of understanding gravity and air resistance. The experiment has since become an iconic representation of scientific inquiry and experimentation.

Key Facts
Date: August 2, 1971
Location: Hadley Rille, Moon’s surface
Objects: 1.32 kg aluminum geological hammer and a falcon feather
Height: Approximately 1.6 meters above the lunar surface
Result: Both objects fell at the same rate, striking the surface simultaneously

"What about Reality? Some say (in popular accounts) the electron is simultaneously both spin up and spin down. This is absurd, as Dyakonov highlights.

"Yes, quantum mechanics often defies intuition. But this concept shouldn’t be couched in such perplexing language. Instead, think of a vector positioned in the x-y plane and canted at 45 degrees to the x-axis. Somebody might say that this vector simultaneously points in both the x- and y-directions. That statement is true in some sense, but it’s not really a useful denoscription. Describing a qubit as being simultaneously in both [UP] and [DOWN] states is, in my view, similarly unhelpful. And yet, it’s become almost de rigueur for journalists to describe it as such. [I can’t get the arrow html to stick, so put in up and down.]

"That vector is a wonderful analogy, and it can be carried much further. About that, more another day."

The Rhetoric of London Larry

The British are gradually beginning to realize that they have bitten off far more than they can possibly chew, and that their time-honored method of providing the decisive force to help one side or the other have the advantage in the conflict is not going to work in the current situation: Putin’s aim is not […]

"When I say Quantum Computing is a bullshit field, I don’t mean everything in the field is bullshit, though to first order, this appears to be approximately true. I don’t have a mathematical proof that Quantum Computing isn’t at least theoretically possible. I also do not have a mathematical proof that we can or can’t make the artificial bacteria of K. Eric Drexler’s nanotech fantasies. Yet, I know both fields are bullshit. Both fields involve forming new kinds of matter that we haven’t the slightest idea how to construct. Neither field has a sane ‘first step’ to make their large claims true."

🇮🇱🇮🇱 IDF sends enlistment notices to ultra-Orthodox Jews

In Israel, the recently appointed defense minister, Yisrael Katz on Friday gave the go-ahead for 7,000 draft notices to be sent to ultra-Orthodox Jews, also known as Haredim, calling them up for enlistment in the Israel Defense Forces. The move aims to “ease the burden on regular, career, and reserve soldiers,” a statement from the ministry said, adding that the military would provide support to the Haredim in “maintaining their religious lifestyle.”


The ultra-Orthodox population makes up more than 12% of the population and have lent crucial backing to Prime Minister Benjamin Netanyahu, who has promised them exemptions from military service. But Israel’s expanding wars have fueled demandsfrom across the domestic political spectrum for a change to the status quo, with the issue threatening to topple Netanyahu’s fragileruling coalition.

“Anyone required to enlist must receive an order. We are at war,” former army general Benny Gantz, said on X in a statement welcoming the move. Opposition leader Yair Lapid also offered his “respect” for the decision.
