How tall should a 12 year old be? What height is considered a giant? What is pico laser technology? How big is the 'Oumuamua? What is a centimeter? How many centimeters are in 2 meters? How do you convert 345 cm to inches?
Cannabis is a weed in the wild that adapts to many climates. Cannabis plants can actually be really easy to grow if you have the right information and know what to do. It can seem impossible to get started if it’s your first time growing, but this website will walk you through every...
which are in many cases the initiating event for health effects . . . We know that microplastics can cross the barriers of cells and also break them, We know they can also cause oxidative stress on cells, which is the start of tissue damage.”– Evangelos Danopoulos...
Photo: Human hair imaged with a 3D laser microscope 250x magnification. The eye of a fruit fly is also 70 microns across. But the eye itself isn't the smallest unit: each eye is madeup of 760-unit eyes that are about 5 microns in diameter each!This is similar to the placement toleran...
The production of infectious aerosols can vary wildly between individuals—and experts are exploring why in the COVID-19 era.
This 41mm steel example with gray dial has a satin polished bezel, complete with beveled edges, which sits atop a 9.7mm uniquely shaped case and is fixed in place with screws; it is water resistant to 100 meters. The crown is signed with a compass rose motif located at three o'clock,...
When I was a child, my handwriting was like a group of ants crawling on the ground, but now my handwriting is clean. I hated reading when I was a child, because I thought there were too many words and no pictures in the book. What about now? Hehe, reading seems to be a part of...
An ordinary light microscope uses photons of light, which are equivalent to waves with a wavelength of roughly 400–700 nanometers. That's fine for studying something like a human hair, which is about 100 times bigger (50,000–100,000 nanometers in diameter). But what about a bacteria ...
By comparison, the fibers in a HEPA filter are roughly 0.002–0.5 microns (2–500 nanometers, nm) in diameter. [1]Artwork: HEPA filters screen out truly tiny particles, even smaller than 0.3 microns (blue line, bottom), which is 10–30 times smaller than PM10 and PM2.5 soot pollution ...
A human hair is anywhere from about 20 to 180 micrometers thick, or in other words 20,000 to 180,000 nanometers. The feature size on the latest AMD and Intel processors meanwhile is around 7nm to 70nm (depending on which specific feature we're talking about). Even a tiny speck of ...
