But our Moon is different. Its orbit doesn’t lie in the plane of the ecliptic. Instead, it’sinclined at about 5°. (How it got that way is unknown, but it’s presumably related to how the Moon was formed.) But that 5° is what makes eclipses so...
We like to think of the periodic table of the elements as immutable. It isn't. Its nether regions have for some time beenfilling up with new elementsthat physicists have forged from smaller atoms. Now even its more mundane areas, populated by familiar, everyday elements, are undergoing a f...
Since I’ve written before about theevils of memorization, it’s now time to put in a good word on its behalf. Specifically, I’d like to share the rhyming catch-phrase I just invented: A little baby-voiced, I realize. But hear me out. ...
Therefore, the next stage was the creation of object-oriented programming languages. When you first build a domain language and then use it to solve an applied problem. For example, in the case of a game: first we create objects of the game world, and then we assemble the game itself fr...
marking, it indicates a possible sun or moon eclipse. the way of setting dates on the device is a bit funky (after all, the modern calendar wouldn’t be invented for another 1500 years), but if one takes the simulation on the wolfram demonstrations project (which was calibrated back in ...
During the sixteenth century, astronomy was the field in science which could be perceived as the pivotal field where traditional forms of seeking for knowledge were questioned and the principles of modern science were developed. The main reason was that observation (of the movement of the stars) ...
Before modern metalworking techniques were invented, blacksmiths used heat to make metal workable. Once the metal was formed into the desired shape, the heated metal quickly was cooled. Quick cooling made the metal harder and less brittle. Modern metalworking has become much more sophisticated an...

It is always interesting to study the influence of a well-localized impulse-like source; therefore, we tried the Lorenzian form and luckily found highly non-trivial solutions. As a second interesting system, the effect of periodic driving was investigated. It looked logical that for a traveling...
