This is what climate change and sea level rise looks like.

It's not some slow, gradual process. It's going to be sudden and catastrophic when it happens.

You know who are the people behind this? Israelis and Zionist groups such as Canary Mission and Betar. Because academics chose to stay silent during a 14 month long genocide, these groups are now emboldened enough to go after any and all perceived enemies of Israel.

This broke your heart, but your heart was not broken seeing the pictures of children shredded by American bombs during 14 months of a genocide?

I have ZERO sympathy for American academics who CHOSE to stay silent when it really mattered.

The reason Trump can destroy America's civil liberties with impunity, is because Americans chose to keep silent when horrific crimes were being committed by their country abroad. There is a direct straight line from the genocide in Palestine to the ICE abductions in the US.

I can imagine this having a lot of applications in everything from photonics to manufacturing. It's the sort of thing which becomes the lynchpin of major new tech frameworks in years to come.

There's a straight line from the shredding of children by American bombs in Gaza to Trump and Musk's shredding of Americans' constitutional rights. But, as long as Americans are happy with the one they will have to accept the other too.

From p.1 of https://math.jhu.edu/~eriehl/context.pdf:

In 1941, Saunders Mac Lane gave a lecture at the University of Michigan in which
he computed for a prime p that Ext(Z[
1
p
]/Z, Z)  Zp, the group of p-adic integers, where
Z[
1
p
]/Z is the Prรผfer p-group. When he explained this result to Samuel Eilenberg, who had
missed the lecture, Eilenberg recognized the calculation as the homology of the 3-sphere
complement of the p-adic solenoid, a space formed as the infinite intersection of a sequence
of solid tori, each wound around p times inside the preceding torus. In teasing apart this
connection, the pair of them discovered what is now known as the universal coefficient
theorem in algebraic topology, which relates the homology Hโˆ— and cohomology groups H
โˆ—
associated to a space X via a group extension [ML05]:
(1.0.1) 0 โ†’ Ext(Hnโˆ’1(X),G) โ†’ H
n
(X,G) โ†’ Hom(Hn(X),G) โ†’ 0 .
To obtain a more general form of the universal coefficient theorem, Eilenberg and Mac
Lane needed to show that certain isomorphisms of abelian groups expressed by this group
extension extend to spaces constructed via direct or inverse limits. And indeed this is the
case, precisely because the homomorphisms in the diagram (1.0.1) are natural with respect
to continuous maps between topological spaces.

So Mac Lane and Eilenberg invented category theory so they could prove the universal coefficient theorem, which they discovered because Saunders showed an algebra computation to Sammy and Sammy went "Huh. That's how I compute the complement of the p-adic solenoid inside a 3-sphere."

The "soul" of the university was given up long ago when they let NYPD in to arrest non violent students protesting the American-Israeli genocide in Gaza. The fact that this is still not obvious to so many Americans is symptomatic of where the country is today.

Fascism is not "coming" to America. It's already there. And Americans paved the way for it by allowing Zionists to control every aspect of their public and political lives.

If Americans had been more conscientious about standing up against Israel's crimes in Palestine, then maybe Trump would not have become President. The American public paved the way for him by choosing to celebrate the superbowl and oscars when children were being shredded by American bombs.

If there is any decisive nail in the coffin of the assertion that Musk is a savant/genius, it should be this. Not having radar/lidar on a self-driving car for detecting obstacles is essentially telling the drivers to say "Hail Mary" and hope everything works out.

You mean to tell me that they're building "self driving" cars which don't use ANY radar tech for sensing obstacles? Why would anybody buy a Tesla at this point for any reason other than if they're a Musk fanboy/girl ?

My response to the editor, hard core string theorist Christopher Herzog, on rejecting my paper without sending it for review.

Too much?

String theory has become a cult sadly. Logic and reason will not penetrate through to them.

Do string theorists really think that by preventing open discussion and publication of research which questions their central dogma, they will manage to halt the precipitous decline in the social and academic relevance of their field?

They've fooled the world for decades now. It won't last long.

Why is this so surprising? These universities already bent the knee in front of Zionist fascists. Now they're bending the knee in front of the "America first" facists. Don't blame the fascists. Blame those so quick to bend in front of power.
