Whale evolution through deep time

The evolution of mammals that live in the sea (whales, dolphins, and porpoises) are of particular interest because they went from ocean to land and then back to the ocean again. There are many depictions of the first stage but fewer of the second. This animation by artist Jordan Collver shows the second stage of the evolution of the sperm whale, from the amphibious Pakicetus to its present form.

Theological spin on scientific discoveries

After posting earlier today about the detection of when the cosmic dawn (i.e., the appearance of the first stars) occurred, I started thinking about how religious people would react to news like this, especially those religions that have anthropocentric views of the universe, like the Abrahamic religions that have the Genesis story as their foundational myths

March came in like a lion alright

The winter in Cleveland has been relatively mild so far, and the last two weeks in particular saw warm temperatures and no snow at all. The forecasts seemed to indicate that this would continue but just yesterday the forecast changed suddenly because of the emergence of a storm in the northeast and we had a major snowstorm last night that dumped a large amount of snow on the ground as we slept.

No evidence that Planck graininess slows down light

Last October, I had a post that looked at the units known as the Planck length, Planck time, and Planck mass and discussed the question of whether these were just a universal set of standards that replaced the traditional ones of meter, second, and kilogram or foot, second, and pound, or whether they had a more fundamental significance. I pointed to a paper that suggested that the Planck length might represent a fundamental limit to the continuity of space, that at that level space ceased to be continuously divisible and became like a foam.

Shaolin monk pierces glass with a needle

The Shaolin order of monks in China is noted for its rigorous training that enables them to perform quite incredible feats of strength and endurance. They are also known for being fierce kung fu warriors, strange for Buddhist monks who are supposed to be pacifist. So how did that happen? Kallie Szczepanski provides a brief summary of the turbulent 1,500 year old history of the order that mixes legend with facts.

The dawn of the universe

Following the initial Big Bang, the universe was at incredibly high temperatures but then underwent a period of rapid expansion and cooling and largely became a cold gas of hydrogen. The universe could be considered to be dark at this time since there was no source of light. But at some point, matter started to clump together under the force of gravity and form embryonic stars and the hydrogen atoms started to fuse into helium, releasing energy, some of it in the form of visible light. This moment is referred to as the ‘cosmic dawn’ of the universe.
