- noun A sponge-spicule of the monaxon uniradiate type, sharp at one end and not at the other. It is regarded as an oxea one of whose rays is suppressed.
- noun In entomology, a style or stylet.
- noun In a phonograph, a pointed part which rests on the diaphragm and is moved by the vibrations induced in the latter by sound-waves. It is used to produce the record of sounds upon the phonographic cylinders, and also to reproduce the sounds thus recorded.

- noun An instrument for writing. See
style, n., 1.
- noun That needle-shaped part at the tip of the playing arm of phonograph which sits in the groove of a phonograph record while it is turning, to detect the undulations in the phonograph groove and convert them into vibrations which are transmitted to a system (since 1920 electronic) which converts the signal into sound; also called
needle. The stylusis frequently composed of a hard metal or of diamond.
- noun The needle-like device used to cut the grooves which record the sound on the original disc during recording of a phonograph record; it is moved by the vibrations given to the diaphragm by a sound, and produces the indented record.
- noun (Computers) A pen-shaped pointing device used to specify the cursor position on a graphics tablet.

As video creator cosmos92 himself notes in the introduction, a stylus is “completely unnecessary” for this device.
Picking a character involves moving the stylus from the stamen into a petal, and then back to the stamen (in some cases via another petal).
Vertical adjustment of the stylus is controlled by means of what is termed the tunnel effect - hence the name of the instrument.
Obviously if the tip of the stylus is too sharp, it rapidly becomes destroyed.
This means here that if the tip of the stylus is near enough to the surface (10 Å, i.e. 1-2 atom diameters) a current flows even at low voltages.
Piezoelectrical elements are used to control the horizontal movement of the stylus in two perpend icular directions so that it scans the surface a long parallel lines - hence the name scanning microscope The vertical movement of the stylus is controlled and measured using another piozoelement.
The stylus is also extremely sharp, the tip being formed of one single atom.
The stylus is short but solidly built with metal and hard plastic.
The stylus is a big plus, at least for users who like to jot down notes, create sketches or annotate documents in a way that's much more precise than using a fingertip.
However, I can see where some folks might consider the 5-inch screen a good trade-off for much better portability than other tablets, and Samsung has done some very interesting work in making the stylus, which is stored in a slot on the device, useful.
