The COVID-19 pandemic has led people to wear face masks daily in public. Although the effectiveness of face masks against viral transmission has been extensively studied, there have been few reports on potential hygiene issues due to bacteria and fungi attached to the face masks. We aimed to (1)...
Considerable thought is given to what events constitute “true” irony, and the dictionary is often called upon to supply an answer. Here are the facts about how the word irony is used.
Irony has two formal uses that are not as common in general prose as its more casual uses. One refers to Socratic irony—a method of revealing an opponent’s ignorance by pretending to be ignorant yourself and asking probing questions. The other refers to dramatic irony or tragic irony—an incongruity between the situation in a drama and the words used by the characters that only the audience can see. Socratic irony is a tool used in debating; dramatic irony is what happens when the audience realizes that Romeo and Juliet’s plans will go awry.
The third, and debated, use of irony regards what’s called situational irony. Situational irony involves a striking reversal of what is expected or intended: a person sidesteps a pothole to avoid injury and in doing so steps into another pothole and injures themselves.
Bluetooth is based on radio with frequencies at 2.45 GHz. Divide the speed of light by 2.45 GHz and you get 122 mm, the typical size of bluetooth antenna. With some clever engineering these antennas can be made as small as about 14 mm, an order of magnitude reduction! Red blood cells have diameters no larger than 0.009 mm, white blood cells have diameters no larger than 0.015 mm. To have bluetooth antennas in blood cells would require 5 (five) additional orders of magnitude of clever engineering to create so tiny a structure that is resonant at 2.45 GHz with more than 100 MHz bandwidth and more than 50% efficiency. (That's the literal definition of a bluetooth antenna: "Any structure that is resonant at 2.45 GHz with bandwidth more than 100 MHz and efficiency >50% can be considered a Bluetooth antenna.") It's not a thing that exists because the very idea is nonsense. If you actually wanted to send messages to/from a cell-sized thing, you would use a wave with a cell-sized wavelength. The problem with that is the human body is mostly water, and liquid water strongly absorbs radiation at these wavelengths.
In summary: Bluetooth bloodcell antennae is a laughable idea appeals only to the arrogantly, confidently, defiantly ignorant.
