"A typical cumulus cloud weighs approximately 1.1 million pounds (\(500,000\) kilograms), about the weight of 100 elephants. This weight is calculated by multiplying the cloud's volume by its water density, which is only about 0.5 grams of water per cubic meter. Although massive, clouds float because the air within them is less dense than the surrounding dry air."

"Some molecules can be very big, but most are still microscopic. Not the vulcanized tire, though — it’s all one, big, freakin’ molecule! Basically, the vulcanized tire is all made of large polymers chains that have been crosslinked together with covalent bonds."--- https://www.zmescience.com/feature-post/...try-facts/

"The sciatic nerve is the largest and longest nerve in the human body, originating at the base of the spine and running along the back of each leg into the foot. At its thickest point, it is about as wide as an adult thumb."--- https://www.spine-health.com/conditions/...ve-anatomy

"In the void of space, where silence reigns and air is absent, a bizarre phenomenon lurks: cold welding.

Imagine two pristine pieces of the same metal brushing against each other—no heat, no tools, just contact—and they fuse instantly, as if they were always one.

This isn't science fiction; it's cold welding, a quirk of physics born from the absence of Earth's protective atmosphere. On our planet, metals oxidize quickly, forming invisible barriers that prevent such unions.

But in a vacuum, unoxidized surfaces allow atoms to bond seamlessly, turning separate parts into a stubborn whole.

NASA knows this all too well. During the Galileo mission, antenna components cold-welded shut, nearly dooming the spacecraft's data relay. Hubble's repairs demanded special coatings to avoid the same fate.

Cold welding challenges engineers, forcing innovative designs for satellites and space stations. Yet, it reveals the universe's raw intimacy—metals merging like long-lost lovers."

"In zero gravity, a candle flame forms a small blue sphere instead of the familiar teardrop shape.

Without gravity, hot air doesn’t rise, so the flame no longer stretches upward.
Instead, gases spread evenly in all directions, creating a smooth, round flame.

This environment allows the fuel to burn more completely, which is why the flame appears blue and produces no soot.

The result is a calm, gentle orb of fire that behaves very differently from a candle flame on Earth."

"Scientists have estimated the minimum lifetime of the electron is about 6.6 × 1028 years – this is 66,000 ‘yottayears’. Since this is about 5 quintillion times the age of the Universe, even if electrons don’t live forever, they may as well do!"
