Immigrant American Superheroes   Leave a comment

Here’s a thought I had for today, since it seems there’s an element of American society terrified of the very portion of the Earth’s population that made the United States a successful nation. That, my folks, would be immigrants. It’s what made this nation great, and will continue to do so. It’s very important to remind ourselves of this, especially if one witnesses the horrific events taking shape in the United States today.

I’ll start off with one very important immigrant: Albert Einstein.

This immigrant was born in Ulm, Germany and came to the United States in 1933, a direct result of the atrocities unfolding in Europe. Nazis were conducting nuclear research with the intent of creating military weaponry. Einstein realized the potential of the catastrophic forces a nuclear bomb would unleash, and wrote President Roosevelt about it. Though it didn’t stop the eventual creation and bombing of Hiroshima and Nagasaki, he remained a pacifist and spent the rest of his life active in humanitarian causes. Seeing the parallels between Jewish atrocities and the Holocaust and the battle for civil rights unfolding in America, he joined the National Association for the Advancement of Colored People (NAACP).

No…he didn’t invent that car, but it’s named after him: Nikola Tesla.

Nikola Tesla American Inventor

Born in Croatia in 1856, he came to the United States in 1884. He’s responsible for inventing alternating current electrical system, or AC – the way electricity is delivered to your house. An early partnership with Thomas Edison didn’t work out, but a later one with George Westinghouse did. Westinghouse purchased Tesla’s patent and eventually AC triumphed over Edison’s direct current electrical system, or DC. AC enabled electricity to be delivered over long distances, while Edison’s DC did not. Tesla also set the groundwork for long-distance wireless communication, but Guglielmo Marconi ultimately beat him to the punch with his radio communication technology. Tesla’s also known for his famous coil, still used in radio technology today.

Here’s an esteemed Nobel Prize winning physicist who also came from Germany: Maria Goeppert-Meyer.

Born in Kattowicz (now Katowice, Poland) in 1906. In 1930, she married American chemist and professor Joseph Mayer. Although it was difficult for a female scientist at that time to gain a foothold in the scientific community, she nevertheless published an important paper on double beta decay in 1935 while holding an assistant position at Johns Hopkins, where her husband worked. She also conducted early work in quantum sciences, and eventually came to Columbia University for an unpaid position, but during that time, she collaborated with Enrico Fermi, who tasked her to investigate the valence shell of the undiscovered transuranic elements. In 1942, she joined the Manhattan Project at Columbia  to investigate separating the fissile uranium-235 isotope in natural uranium. Goeppert-Meyer developed a mathematical model for the structure of nuclear shells. For this, she was awarded the Nobel Prize in Physics in 1963 (sharing it with J. Hans D. Jensen and Eugene Wigner) and became the second female Nobel Prize winner after Marie Curie.

There are many, many others, of course, who have contributed in science, art, literature, politics, education, commerce and more. Since this country came to be as the result of immigration, each and every person who arrives upon our shores has much to contribute in making this country an example of what can be achieved…if we allow it.

Gravitational Waves

It’s all over the internet: Einstein was right – there are such things as gravitational waves.

In a seemingly impossible experiment, a group of astrophysicists announced on Thursday, February 11, 2016 that they now had aural evidence of gravitational waves. An international mega-group of 1000 scientists published a report in Physical Review Letters confirming their findings.

For those of you who might be asking, “What are gravitational waves?”, here’s a quick definition. They’re ripples in spacetime created by any particle or object with mass. Einstein predicted them in his theory of relativity in 1916.

In a classic case of “if a tree falls in the woods, does it make a sound,” two black holes collided so impossibly far away – a billion light years – and only now is the Earth receiving the noise from that cataclysmic event.

Two antennas designed for receiving any sound a gravitational wave would generate, located in Washington State and Louisiana, and part of LIGO (Laser Interferometer Gravitational-Wave Observatory), picked up a brief chirp on September 14, 2015.

This event’s also a significant achievement for astronomy, where so much is dependent upon what can been seen. This experiment delivers another dimension from which to observe and measure the universe.
