Moshe Kai Cavalin (b. 1998) was born in Los Angeles, the son of a Taiwanese mother and an Israeli-Brazilian father. He started speaking at 4 months of age, and was reading and doing math by 3. At 6, he was rejected from elementary school because he “knew more than the teacher”, and had to be home-schooled. At 8, he became the youngest person in American history to take college classes. He got his first degree three years later, with a perfect 4.0 GPA. He then enrolled at UCLA – with a full scholarship – and earned a BS in mathematics. Meanwhile, Kai wrote two bestselling books (an inspirational autobiography, and a manual to deal with bullying). For fun, he scuba dives, plays piano, and chess, and avoids video games which, he says, are “not helping humanity in any way.” He is also an avid martial artist – thanks to his father, a former IDF special forces commando – and has won 26 gold medals. Incredibly, Kai got a pilot’s license, too. This led to a phone call from NASA in 2015. NASA needed a pilot who also knew math, physics, and computer programming to develop surveillance and anti-collision technology for drones and airplanes. Kai has been at NASA ever since, working hard to keep the skies safe. He is concurrently doing his Master’s in cybersecurity, and intends to later get a Master’s in business from MIT before opening his own cybersecurity company. Kai describes himself as a religious person and often credits God with giving him the insight to solve problems. One of his professors once said: “I think most people just think he’s a genius, they believe it just comes naturally… He actually worked harder than, I think, any other student I’ve ever had.”

Science without religion is lame, religion without science is blind.

Vera Cooper (1928-2016) was born in Philadelphia. Her parents were Jewish immigrants from Eastern Europe (who changed their last name from Kobchefski to Cooper). From the young age of just 10, Cooper was interested in astronomy, and was later the only woman studying the subject in her college. She intended to continue graduate studies at Princeton but was forbidden because of her gender. Cooper went to Cornell University instead and studied astrophysics and quantum physics. There she also met her husband, Robert Rubin, who was pursuing graduate studies in chemistry. The two had four children, all of whom became Ph.D scientists and mathematicians. Rubin completed her Master’s in 1951 and went to Georgetown University for her doctorate. Around this time, she discovered that whole galaxies are rotating around their centres – an idea so revolutionary that it was initially rejected. Her 1954 Ph.D thesis was similarly revolutionary, showing that galaxies must be clumped in clusters. No one paid attention to this work for another two decades, when it was confirmed to be true. In 1965, Rubin was the first woman allowed to use Caltech’s famous Palomar Observatory. She then became a Senior Fellow at Washington’s Carnegie Institution, where her research was focused on “galactic and extragalactic dynamics”, among other things. Rubin made critical calculations with regards to galactic rotation rates, and together with her friend Robert Ford, discovered what is now known as the Rubin-Ford effect. In her studies, she found that galaxies are spinning so fast that they should be flying apart. They do not fly apart because gravity keeps them together. But, there is not enough visible matter in galaxies to generate so much gravity! This led Rubin to confirm the existence of invisible dark matter. This was perhaps her biggest breakthrough, and completely transformed astrophysics. For her tremendous achievements, Rubin has won multiple awards, including the National Medal of Science and the Royal Astronomical Society’s prestigious Gold Medal. There is also an asteroid named after her. Sadly, Rubin passed away earlier this week. Despite being 88 years old, Rubin continued her scientific research (focusing on the motion of distant stars) until the last days of her life. She was a pioneer for women in science, and worked tirelessly to get more women elected to the National Academy of Sciences. Rubin was proud of her Jewish heritage, and often spoke of the beauty and value of science and religion when studied together. In addition to half a dozen important scientific publications, Rubin wrote a book, and was featured in two documentaries. She was once described as an American “national treasure”.

The first gulp from the glass of natural sciences will turn you into an atheist, but at the bottom of the glass God is waiting for you. – Werner Heisenberg, Nobel Prize-winning physicist
Carl Sagan (1934-1996) Born to Russian-Jewish immigrants in Brooklyn, Sagan went on to become one of the greatest and most beloved scientists of the last century. He published more than 600 scientific papers and at least 20 books, one of which was the novel Contact, since adapted to a Hollywood blockbuster. He is most famous for being the host of the popular 1980s TV show Cosmos. Sagan had degrees in physics, astrophysics and astronomy, lectured at Harvard and was a full-time professor at Cornell. One of the central figures at NASA, Sagan helped develop many space missions, and designed the famous golden plaque launched with most space crafts. When asked if he was an atheist, Sagan replied “An atheist has to know a lot more than I know. An atheist is someone who knows there is no god. By some definitions, atheism is very stupid.”
