Paula Kelly died.


You may remember her as the public defender on Season 1 of Night Court.
Or the lab tech in Andromeda Strain.

The name is derived from Old English Þūnresdæg and Middle English Thuresday (with loss of -n-, first in northern dialects, from influence of Old Norse Þórsdagr) meaning "Thor's Day". It was named after the Norse god of Thunder, Thor.

Time is an illusion.

Time is when the particles of the universe were arranged in a particular order. If those particles could somehow stop rearranging themselves, or go back to a previous arrangement, then Time has no meaning.

Yea, I get what you're saying. But, isn't time also just somthing that we reference as we get older? So, your concept of the past is going to be much different than mine because of our life experiences. That is why there is no past, and no future. Our thoughts are making it all up thru social conditioned thinking. There is only NOW, the present.

WD-40 was invented in 1953.


It was never patented so they would not have to disclose their formula.
Lovely stuff (from Wired Mag -2009)
Mineral Oil
Seriously. WD-40 is mostly a mix of baby oil, Vaseline, and the goop inside homemade lava lamps.

Decane
WD-40 contains an abundance of alkanes—hydrocarbons that match the formula CxH2x+2, usually in a long, zigzagging chain. This one, C10H22, which is also a common ingredient of gasoline, helps WD-40 remain a liquid at cold temperatures. Decane doesn't freeze until around -21 degrees Fahrenheit.

Nonane
Another alkane. One reason these molecules are so handy here: Their hydrogen atoms don't hold a charge, so they can't connect to the hydrogen or oxygen in water, which makes alkanes water-repellent. WD-40, after all, stands for "water displacement, 40th attempt."

Our lab analyzed WD-40 with gas chromatography (GC) and mass spectroscopy (MS). GC separates chemicals based on size, boiling point, and other factors, releasing them one by one over time. MS then blasts the molecules with an electron beam and tells what's what by the mass of the ionized fragments. Tridecane and Undecane
Freeze-resistant? Check. Water- repellent? Check. Contains an alkane that is the major product of the red-banded stinkbug's scent gland? Check! Many alkanes are naturally produced by living creatures. Undecane, part of the pheromone trail left by cockroaches and ants, is present.

Tetradecane
Another alkane! Zzzzzz.

Dimethyl Naphthalene
Here's the thing: This stuff (C12H12) comes in 10 forms, called isomers. One of them is a harmless hormone given off by potatoes. Another is used in high-performance engineering plastics. Our analysis can't determine which ones are present here, but if you're using it as a solvent, as is likely the case with WD-40, they all work just fine.

Cyclohexane
That cyclo prefix means that unlike standard alkanes, which come in chains, this one's a ring. The shape gives cycloalkanes a higher melting point. And huffing them will knock you out cold. (Or so we're told.)

Carbon Dioxide
The WD-40 company claims that by using this gas as a propellant, it avoids using smaller gaseous alkanes (possibly butane and propane), which can be hazardous to the environment. As if CO2 isn't.
