There was an almost simultaneous and independent invention of the device by the Austrian Simon Ritter von Stampfer, which he named the "Stroboscope", and it is his term which is used today. The etymology is from the Greek words στρόβος - strobos, meaning "whirlpool" and σκοπεῖν - skopein, meaning "to look at".
It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek στρόβος ( stróbos ), meaning "act of whirling". A typical commercial strobe light has a flash energy in the region of 10 to 150 joules , and discharge times as short as a few milliseconds, often resulting in a flash power of ...
Consider the stroboscope as used in mechanical analysis. This may be a "strobe light" that is fired at an adjustable rate. For example, an object is rotating at 60 revolutions per second: if it is viewed with a series of short flashes at 60 times per second, each flash illuminates the object at the same position in its rotational cycle, so it ...
When it was introduced in the French newspaper Le Figaro in June 1833, the term 'phénakisticope' was explained to be from the root Greek word φενακιστικός phenakistikos (or rather from φενακίζειν phenakizein), meaning "deceiving" or "cheating", [2] and ὄψ óps, meaning "eye" or "face", [3] so it was probably intended loosely as 'optical deception' or 'optical illusion'.
Sweet meets savory in Trader Joe's seasonal peppermint-crunch popcorn, which mixes dark- and white-chocolate-coated kernels tossed in crushed candy canes.
Domestic cats are peculiar creatures. Adorable but deadly, they act as lovable companions in the home and as a scourge to vermin and bird populations in the yard. They are simultaneously ...
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
An old method of measuring the frequency of rotating or vibrating objects is to use a stroboscope. This is an intense repetitively flashing light (strobe light) whose frequency can be adjusted with a calibrated timing circuit. The strobe light is pointed at the rotating object and the frequency adjusted up and down.
