June 19, 1926, a letter written by Hendrik Antoon Lorentz to Erwin Schrödinger concerning wave quantum mechanics.
In this correspondence, Lorentz, at the age of 73, demonstrates his profound command over the newly established wave mechanics, leaving a significant impression on its originator, Schrödinger.
I found this amazing integral on Mathematica Stack Exchange. It was interesting and tricky. Here’s my solution and how could we extend the result to a more general integral?

@khoyriyahasadah@acknowledgome blum ka. Aku sejauh ini baru cuman beli tombol daya+volume+fleksibel (dari shopee), masih blum nemu servis konter cocok.
Kakak udah nemu cara?
A remarkable paper appeared on arXiv tonight by Thomas Bloom, Will Sawin, Carl Schildkraut and Dmitrii Zhelezov. In this paper, they prove that there exists c>0 and arbitrarily large finite sets A of real numbers such that max(|A+A|,|AA|)≤|A|^{2-c}. This disproves the well-known sum-product conjecture over the real numbers. The sum-product conjecture considers the two most basic operations: addition and multiplication. A+A is the set of all pairwise sums of two elements in A while AA is the set of all pairwise products of two elements in A. (1/5)
