Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?Continue reading
The evening of November 9th, 1938, began with typical fall solemnity for many Jews living across Germany: closing up their shops and businesses, returning home from school, and preparing family suppers. It would end with terror, as mobs ransacked storefronts, assaulted Jews on the street, and set fire to their homes. That terrible night would be known to history by the glittering debris of shattered windows lining the streets: “Kristallnacht.”
Kristallnacht, and the subsequent atrocities of Germany’s holocaust against the Jews, changed the world. Modernity had to forever acknowledge a surprising and abhorrent crime. Societies would undergo lasting changes, attempting to prevent such crimes, and the victims themselves, sadly, would suffer long-lasting impacts to their psyche.Continue reading
You’re on your way to the traditional Thanksgiving family get-together. You drive down a familiar street, locate your familiar house, and park in a familiar spot.Continue reading
Marine mammals, such as dolphins, whales, and porpoises, spend their entire lives at sea. Like us, they need to breathe, avoid danger, and care for their young. Like us, they need to sleep, which — for us — involves almost total unconsciousness and paralysis. So how do these marine mammals not drown when they sleep?Continue reading
The minds of individuals are like parallel universes, forever inaccessible to one another. Never do we truly see through the eyes of another person. It is common for us to wonder if other people experience the world in the same way we do. Is your green my red? Is my yellow your blue?Continue reading
What are brain waves? It’s no wonder the term sounds like science fiction. In the 1920s, a German psychiatrist embarked on a highly personal quest to discover the supposed medium of telepathy. By placing electrodes on the human scalp, Hans Berger found waves of electrical brain activity using a tool called electroencephalography, or EEG. Physicists had recently shown that electromagnetic waves could propagate through space to carry information. If the brain had its own waves, could they transmit thoughts to others like a radio broadcast?Continue reading
It’s a lazy Sunday afternoon. Professor Freeman is enjoying the Southern California weather on Professor Domino’s patio.
Domino: Will it be Coke or Pepsi, Dr. Freeman?
Freeman: That’s an easy choice, Dr. Domino.Continue reading
Last month, astronomers announced the prediction of a new giant planet in our solar system dubbed Planet IX, a genuine ninth planet with ten times the mass of Earth. The announcement lead to some confusion on the Internet as to the whether the planet had actually been discovered. In fact, no direct observation of this planet has been made. Rather, the planet has been predicted by a model, a simplified description of a system which often incorporates hypothetical elements to explain the variance in data. Because many models use equations to describe a system, a model can often be thought of as a theory with a mathematical backbone.Continue reading
People like simplicity. Each decade, corporate logos grow progressively minimalistic, pop songs use ever simpler melodies, and visual art embraces simpler compositions, as Monet gives way to Picasso and Picasso gives way Rothko. This zeitgeist, summarized as “simplicity is the ultimate sophistication,” shapes our perceptions of physiology in interesting ways. The thumping of a beating heart is often celebrated as nature’s beautifully simple rhythm. Listening through a doctor’s stethoscope, one expects any deviation from perfect rhythmicity to be an omen of disease.Continue reading
