Test your knowledge of light bulbs: how they work, their key components, the science of incandescence, and the role of ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In her biography of milliner Lyndsey Kennett, Hilary E. Hunt describes some of the Kennett family history. Lyndsey Kennett's father, Thomas, was one of three brothers who in 1928 took the lease on ...

How are halogen lamps different? Like with incandescent light bulbs, the electrical current enters the socket and travels to a tungsten filament, heating up the filament to incandescence.

IT has been known for a long time that perfectly pure tungsten cannot be used for the manufacture of filaments for electric lamps on account of its “off-setting” structure due to ...

Rather than the glowing tungsten of Thomas Edison, the filaments are composed of a series of light-emitting diodes strung together in a line and then twisted into artsy spirals for an attractive ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

Energy Beam Sciences, Inc. has ceased manufacture and sales of their tungsten filament product line and Ted Pella, Inc. will commence manufacture of the line soon with sales and service to follow.

Tungsten filaments are not capable of reaching more than about 3300 Kelvin or about 5500 Fahrenheit before the filament melts! Old-fashioned light bulbs are filled with helium, argon or similar inert ...
