Growing up, Meilech Kohn didn’t like it in the Yeshiva. He was the quiet kid who liked to daydream and hum nice tunes, and his fellow students were so miffed by his strange ways that they shunned him altogether, refusing to speak to the awkward child. Increasingly distraught, he retreated into his inner world, which was increasingly consumed by writing songs and melodies. Eventually, he decided to drop out.
Much to the chagrin of his parents, Meilech left the fold of his tightly-knit Hasidic community. He moved to Los Angeles, then Puerto Rico, then Texas. He listened to any kind of music he could find, and continued to teach himself his craft. By the time he was ready to return home and recommit himself to religious life, he contained multitudes.
This past Saturday night, like many observant Jews across the country, I watched the Yankees vanquish the Cleveland Indians in Game Five of the American League Division series. This would be unremarkable except for the fact that the game had been played three days earlier. Thanks to the Jewish holiday of Sukkot and then Shabbat—during which religious Jews eschew electronics—I had completely missed the entire exciting affair. I’d heard the Yankees had won, but did not know the score.
Some might raise an eyebrow at watching a three-hour sporting event when one already knows the outcome. It’s one thing to DVR a game one can’t watch in real-time, avoid all spoilers, and watch it shortly thereafter. It’s another to wait days, know the endgame, yet do so regardless. But I’ve actually been engaging in such retrospective fandom for some time—and not just for games on Shabbat.
“O. Hahn and F. Strassmann have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and caesium. It can be shown by simple considerations that this type of nuclear reaction may be described in an essentially classical way like the fission of a liquid drop, and that the fission products must fly apart with kinetic energies of the order of hundred million electron-volts each.” -Lise Meitner
Now that we’ve observed merging neutron stars for the first time, in many different wavelengths of light as well as in gravitational waves, we’ve got a whole new world of data to work with. We’ve independently confirmed that gravitational waves are real and that we can, in fact, pinpoint their locations on the sky. We’ve demonstrated that merging neutron stars create short gamma ray bursts, and shown that the origin of the majority of elements heavier than the first row of transition metals comes primarily from neutron star-neutron star mergers.
This color-coded periodic table groups elements by how they were produced in the universe. Hydrogen and helium originated in the Big Bang. Heavier elements up to iron are generally forged in the cores of massive stars. The electromagnetic radiation captured from GW170817 now confirms that elements heavier than iron are synthesized in large amounts the aftermath of neutron star collisions.

But the new discovery raises a ton of questions, too. Seeing this event has presented theorists with a number of new challenges, ranging from the event rate being some ten times as great as expected to much more matter being ejected than we’d thought. And what was it that was left behind? Was it a neutron star? A black hole? Or an exotic object that’s in its own class?
We knew that when two neutron stars merge, as simulated here, they create gamma-ray burst jets, as well as other electromagnetic phenomena. But whether you produce a neutron star or a black hole, as well as how much of a UV/optical counterpart is produced, should be strongly mass-dependent.

In 1980, Sesame Street took their viewers on a tour of a saxophone factory, showing each and every step that made the instrument take shape. This fantastic tour was set to an incredible soundtrack of freestyle jazz being performed by an off-camera sax player, who suddenly appeared and proclaimed “Saxophone”
Davie504, the talented bassist who is constantly performing in new and creative ways, successfully answered an online challenge to play a continuous solo on an triple neck bass. This bass was quite unusual as the first neck was fretless, the second had only two strings and the third only three strings. In typical fashion, however, Davie easily conquered the challenge without breaking a sweat.
Playing a Trriple Neck Bass Guitar… 6 strings in total, but on three necks… One neck is fretless.. This is one of the craziest instruments ever!
Baroque and Rococo wigs used to be adorned with symbols of luxury, sophistication and the romantic spirit of the time. They were frequently bedecked with model frigates and intricate still lives composed of exotic fruits, flowers and even stuffed birds. This historic trend inspired us to link our paper Baroque wigs with the similar symbols of our time. We knew at once that we wanted to take up the airplane and the skyscraper as the symbols of our time that are both bright and beautiful. Our new series is a combination of old and new luxury, where the skyscraper rises at the top of an ornate hairstyle, and the plane is decorated with flowers and ostrich feathers.
A nest is a place where you have a sense of protection and strength. It’s like an earth temple or a nature temple. The wood is following a pattern, but not one branch is the same. …I’ve built around 50 nests all over the country, and now primarily, I build the nests with kids within an educational setting. As an educator, like, it’s really important to work with kids and help them realize that they have the ability to shape and create an environment.
While riding in the car with his humans, a cautious umbrella cockatoo began growling when he “spotted some dogs in the neighborhood”. When the car stopped at a light, several dogs hanging out behind a backyard fence saw the bird and began barking. The cockatoo was more than ready for this response and immediately began barking back.
David Locke and Ron Boone breakdown the Jazz 100-97 lost to the Minnesota Timberwolves in a close battle late. Ricky Rubio shows his value, Derrick Favors displays a jump shot but sloppy plays late and mistakes cost the Jazz a chance to win.
