  • Bing Chat is doing quite well:

    That’s an interesting question. Proxima Centauri b is a planet that orbits Proxima Centauri, the closest star to Earth. The planet orbits its parent star at a distance of roughly 4.6 million miles (7.5 million km) with an orbital period of approximately 11.2 Earth days. Proxima Centauri b is only four light years away from Earth.

    A solar sail is a spacecraft that uses the pressure of photons from the sun or other light sources to propel itself. The maximum theoretical speed a solar sail could reach is around 420 kilometers per second, or about 1/4 of the speed of light. However, this would require a very large and thin sail, and a close approach to the sun. A more realistic speed for solar sails is 10% of the speed of light, or 67,100,000 mph.

    Assuming a solar sail could reach 10% of the speed of light, it would take about 40 years to travel to Proxima Centauri b. However, this does not account for the time it would take to accelerate and decelerate the spacecraft, or the effects of gravity from other bodies in the solar system. A more accurate estimate would require a detailed trajectory analysis and simulation.

    I even asked Bing to calculate the time dilation for the person on earth. It answered correctly with the formula and steps shown clearly.








  • The title is very confusing. And the article is like a long essay.

    Here is a summary by Chat GPT:

    The web page is a blog post by a teacher who argues that most kids today can’t use computers effectively. He shares several anecdotes of students and adults who lack basic computer skills, such as troubleshooting, googling, and programming. He criticizes the education system for not teaching computer literacy and problem-solving, and he urges parents and teachers to help kids become more competent and confident with computers. He also warns that relying too much on technology can make us vulnerable to manipulation and exploitation by those who control it.










  • The term “tankie” is a slang term used to describe a person who supports or apologizes for the actions of authoritarian communist regimes, particularly those that have used tanks or military force to suppress opposition or maintain control. The term originated from the Soviet Union’s use of tanks to quell protests and uprisings, most notably the 1956 Hungarian Revolution and the 1968 Prague Spring in Czechoslovakia.

    While there may be varying interpretations and uses of the term, it is generally used pejoratively to criticize individuals who defend or downplay the human rights abuses, political repression, or atrocities committed by these regimes.
