As for who invented the zipper, not everybody agrees. Most people give credit to American Whitcomb Judson. Originally, Judson intended his creation, which he called the "clasp-locker," as a replacement for shoelaces. It didn't quite manage to do that, but, after a series of refinements (it jammed quite a bit early on), the zipper became a hit. The US Army was an early adopter, applying "zippers to the clothing and gear of the troops of World War I."

How old was zacharias when he invented the microscope?
There is a lot of confusion and controversy surrounding the invention of the microscope. If Zacharias Janssen invented the compound microscope on the claimed dates between 1590 and 1618 (most commonly given dates of 1590 and 1595), Janssen could have been a child, or not even born yet, as his birth date has been given as 1580, 1585, and 1588. Janssen was a one time neighbor to Hans Lippershey, another inventor laying claim to the microscope. Testimonies offered from various family and friends have also been inconsistent, so the actual inventor, date, and other details surrounding the microscope are impossible to know for fact. Janssen was a known counterfeiter and fraud on other matters, so it is possible he did not invent the microscope at all.

Why does a paper snake spin when held over a Bunsen burner?
The spinning motion of the paper snake when held over a Bunsen burner is due to convection currents created by the heat rising from the flame. As the air above the flame gets hot, it rises creating a low-pressure area that causes the paper snake to rotate. This is a demonstration of the principle of convection.

Is the laserphaco probe currently in use anywhere?
Having experience from Norway, Denmark and South Africa as a senior ophthalmic surgeon; the answer is no. Having followed different international conferences; the answer is no. In the industrial world, ultrasound-like phacoemulsification is totally dominating. In the developing world, some phacoemulsification is in use, otherwise they just remove the cataract trough a big incision, using only water and suction, called Extra Capsular Cataract Extraction. Sincerely Dr. Thomassen, S.E. Viborg Denmark
