Boson

In particle physics, bosons are subatomic particles which obey Bose–Einstein statistics. Several bosons can occupy the same quantum state. The word boson derives from the name of Satyendra Nath Bose. Bosons contrast with fermions, which obey Fermi–Dirac statistics. Two or more fermions cannot occupy the same quantum state. Picture: Higgs Bosons Since bosons with the […]

Superfluid

Superfluidity is a phase of matter or description of heat capacity in which unusual effects are observed when liquids, typically of helium-4 or helium-3, overcome friction by surface interaction when at a stage (known as the "lambda point" for helium-4) at which the liquid’s viscosity becomes zero. Also known as a major facet in the […]

Paradigm shifts and Science

The word paradigm in the scientific or design professions is used to indicate a pattern, model, outstandingly clear or typical example or archetype. These paradigms are the conceptual frameworks that provide a unified perspective over a range of experiences. Since students mainly learn from and are mentored by others who learned the foundation in their […]

How To Help Your Kids Love Science

One of the toughest things to learn is how to enjoy learning. That sounds a little ridiculous but it’s very true. Children begin to become interested in learning at a very young age. By the time most people are only 4 years old they are discovering more and more about the things they are interested […]

IMAX Hubble 3D & the James Webb Space Telescope

IMAX Hubble 3D, hitting the theaters on March 19, features the most famous space telescope of all, the Hubble, launched in April 1990. Soaring above the earth’s atmosphere, it gives the clearest picture of the universe without atmospheric disturbances. Astronauts were sent to service the telescope on five separate missions, the last in 2009 and […]

Deadly Earthquakes and Tsunamis

It is likely that, within our lifetime, we will see a big earthquake ravage a populated area, such as northern Los Angeles, San Francisco, Tokyo, or Istanbul, to name a few major cities. These are earthquakes waiting to happen. It is inevitable that we will see a big one in the United States. It’s not […]

Albert Einstein: A Person for the Ages

I would put Albert Einstein among the 20 top people who have ever lived, in terms of their impact on our way of life. Kings, queens, and emperors have come and gone, without leaving a trace, but Einstein helped to create the world around us. Time Magazine called him the Person of the Century—I would […]

The Changing Climate

I have often been asked about my thoughts on the recently increased storm activity and global warming. The fact is, you cannot judge a book by its cover, so you cannot make any definitive statements one way or the other about global warming based on current storms, which are primarily local effects. Global warming depends […]

Small-Scale Invisibility Cloaks

For generations, the topic of invisibility has been of great interest. Although it was once dismissed as science fiction, it has now become reality on a small scale. Physics textbooks around the world must be rewritten and scientists must admit that they were wrong. For the first time, scientists in Germany announced that they have […]

Is Time Travel Possible — II

image_thumb.png

As we mentioned in a previous post, Einstein himself was worried about the possibility that time travel was built into his General Theory of Relativity. In 1949, when his good friend Kurt Gödel showed that a rotating universe allowed for time travel, he was deeply worried. Gödel, in fact, would pester astronomers visiting Princeton and […]

Is Time Travel Possible — I

First, let me thank BigThink.com for giving me the opportunity to share some thoughts, insights, and commentary with the digital audience. Second, I would like to use this opportunity to answer some frequently asked questions. One question that keeps recurring is: Is Time Travel Possible? The answer to this question pushes the very limits of […]
