When you need to check the size of something, you don’t always have the best measuring tools on hand. Here are some tips on doing the job with and without rulers: * Use your own body for fast, approximate measuring. The first joint of an index finger is about 1 inch long. When a...

Make a fist, with the back of your hand facing you. The width of your fist will approximately be 10 degrees. This means that any two objects that are on the opposite ends of your fist will be 10 degrees apart. The North Star (Polaris) and Dubhe, one of the northern pointers of the...
Absolute encoders, on the other hand, also record movements while the power is off and return the actual position after power on. Travel to a reference point is not necessary. Absolute encoders are suitable for complex machines or machines with large dimensions. ...

Need to measure, but there's no kitchen jug / measuring cup at hand? Need to weigh, but your scale is missing? Your iPhone will turn any glass, bowl or container into a measurement jug, or kitchen scale! And it also it converts volume, weight, temperature and length! --- This is ...
(Whitney [174]) Every open set E⊂RN can be partitioned into the countable union of closed dyadic cubes {Qn}, with pairwise disjoint interior and satisfying, diamQj≤dist{Qj;∂E}≤4diamQj for all j. 2c Limits of Sets, Characteristic Functions and σ-Algebras 2.1.: From the definit...
These fast time scales are, on the other hand, routinely accessible by spectroscopic techniques such as fluorescence correlation spectroscopy (FCS). To enable the direct investigation of fast dynamics at the relevant spatial scales, FCS has been combined with super-resolution stimulated emission ...
With the increasing availability of the COVID-19 vaccines, vaccination has been rapidly promoted globally as a countermeasure against the spread of COVID-19. In Japan, vaccination was first introduced in February 2021. However, the amount of concern towa
