Clouds are thoughts in the mind of the sky.

Hummus. Halva. Tahini. Sesame would be a difficult allergy. My condolences.

Sharp and short, alternating left and right at about 4 Hz, on the side of the tongue back by the molars. Feels like pulling the side of the tongue away from the teeth. It’s a much clickier click than a front of the tongue ‘click’.

If you can make a clicking noise with the side of your tongue, you can easily sense the volume of space you’re in, how close to a wall, etc.

Yes. The 12 steps are a self directed self paced investigation of self and/in society. The community is welcoming, with diverse backgrounds and experiences. Humility, sharing of suffering and joy, laughter. YMMV

I just want the touchscreen buttons for a choice to be separated on the screen by more than a finger’s width. Every yes/no choice is right next to each other, and driving and hitting 1cm^2 a millimeter away from another 1cm^2 is not good UIX.

Is there enough silver to make 300 TW capacity of solar panels?

I live with and care for a dog. We are coevolved species. Your frame of ‘owning’a pet is not shared by all.

As my wise auntie says,”You can’t see clearly through the bottom of a pint glass.” Are you not drunk on energy? Warm or cool at will, well fed and clothed, able to travel and communicate? There’s no collecting if you bet on the apocalypse. <\wisdomnag>

Reverse that. What is called tin foil is actually always aluminum. Once upon a time, though…

In the context of collecting pollutants, entropy is huge. Big light in sky is source of juicy low entropy energy, true, and the big win is the flux of infrared out. Ten times as many photons to carry away the same energy.

It was a controlled infection with Smallpox, by scraping the skin with pus or scab powder from an infected person. Cowpox is what makes the smallpox vaccine.

It would be pretty boring, proteins bouncing around randomly and occasionally honking up, substrates flying around like rifle bullets sometimes hitting the target, and everything smooshing around in random directions. If you’ve seen Brownian motion, you’ve seen what is happening to all the molecules but at 1/100 the length scale. Nothing stays put. Everything is moving fast and far on the scale of proteins and small molecules.

I was reading that page today, as I am putting together a chapter on using liquid nitrogen in science demonstrations. Thank you, James Dewar, for your marvelous vacuum insulated flask!

I saw it! A tiny, shiny speck under the microscope, and the thrill of seeing a form of matter which, it can be argued, has never existed anywhere in the universe. Ever.
