Custom imprinted science glassware with personal messages or corporate logos is becoming increasingly popular & not just for science and technology companies. Lab beakers are being used as shot glasses and drinking vessels by breweries and distilleries. Weddings see them put into service for holding candy and flowers. Here is an interesting example we recently did. Continue reading
The theory behind how lasers work dates back over 100 years. Einstein’s work on the Photoelectric Effect won him the Nobel Prize; not for Relativity as most people assume. Ted Maiman, while at Hughes Aircraft, built the first working laser using synthetic ruby over 50 years ago.
Consequently, lasers have become powerful tools of the modern age and find use in telecommunications, holography, eye surgery and bar code scanners. Several types have even found their way into printing as described below.
Humans & our primate relatives are unique when it comes to the perception of color. Among the mammals, only we have the ability to see our world in full color. We take this for granted & only when we go to reproduce color images accurately in print & other media do we begin to appreciate how complex this process is. Continue reading

What is more iconic & associated with Sir Isaac Newton, a falling apple or glass prism? One reminds us his work on gravity held sway for centuries until Einstein’s Theory of Relativity. The other informs us of his discovery that white sunlight is made up of a rainbow of colours.
These simple devices still anchor basic physics lab experiments but have found new, unrelated uses.
