2- One who is crazy or deranged.
3- A stupid fellow; a clown: with various shades of intensity as an opprobrious epithet, like fool, dolt, etc.

Warning of a forthcoming collapse of the Atlantic meridional overturning circulation (www.nature.com)

The Atlantic meridional overturning circulation (AMOC) is a major tipping element in the climate system and a future collapse would have severe impacts on the climate in the North Atlantic region. In recent years weakening in circulation has been reported, but assessments by the Intergovernmental Panel on Climate Change (IPCC),...

… at wikipedia :

The Atlantic meridional overturning circulation (AMOC) is part of a global thermohaline circulation in the oceans and is the zonally integrated component of surface and deep currents in the Atlantic Ocean. It is characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder, deep waters. These “limbs” are linked by regions of overturning in the Nordic and Labrador Seas and the Southern Ocean, although the extent of overturning in the Labrador Sea is disputed.[1][2] The AMOC is an important component of the Earth’s climate system, and is a result of both atmospheric and thermohaline drivers.

Thanks, ( I couldn’t figure it out but ) with your help I begin to see it. For me, while “attacks” are bad, “confrontation” is like “constructive criticism”. I believe we need at least some “confrontations” and take those the right way to grow out of mediocrity.

Thanks, I heard of it yet couldn’t find the definition :

Since 1893, the legal definition of the foot in the United States has been based on the meter. The definition adopted at that time was the one specified by Congress in 1866, as 1 foot = 1200/3937 meter exactly (or 1 foot = 0.304 800 6 meter approximately).

And now USA will use :
1 foot = 0.3048m
…much more convenient 😆 !

What if solving interstellar travel isn't about figuring out faster than light propulsion, but how to extend our own lives?

So I was day dreaming and I caught a thought. What if what we understand about physics is actually all there is to understand?

This would mean that the only way to travel amongst the stars would be to...

Built a machine that can repair itself. Send it to a nearby planet. Give it the ability to manufacture human embryos from our genetic code using only inorganic material. Make at least 2 ; let’s call them Adam and Eve. Keep this machine somewhere hidden and near them so to guide them and their offsprings for a few milleniums. Someday, if they are mature enough, tell them what happened.

Most interesting indeed.
So the cost of energy is a complex topic and this guy has studied many aspects of that.

Amongst other things he wrote :
Morgan, Tim (2013). Life After Growth. Petersfield, UK: Harriman House. ISBN 9780857193391

He discusses the energy cost of energy or : Energy return on investment

He gives an estimate of $130 trillion usd for the global cost of energy transition with a link to the source… I don’t understand how this estimate is made though.

Every day the Earth receives 50 tons of radioactive material from the Sun, so, can we see this in a global perspective : what are the numbers ?
( sorry if this is a double : server is lagging because of DDOS attack )

A_A , (edited )
@A_A@lemmy.world avatar

That 50 ton per day I recalled from long ago. So I had to make some search, here’s what I found :

  1. Ground Level Enhancement
    These effects are usually measured as elevated levels of neutrons and muons. These events can increase the radiation dose of an individual at sea level or while in an aircraft, though not by enough to significantly increase an individual’s lifetime risk of cancer. …and
  2. "solar wind"
    400 km/s x 5 ions/cm^3^ x 1g/mol x …(6400km)^2^ x 3.1416 x 1e15cm^3^/km^3^
    … x 86400s/day x 1/(6.02e23 ions/mol) This is about 37 tons per day, mostly proton and alpha particles.

    I used the diameter of the earth instead of that of the magnetic field around the Earth, this is simplistic but should give an order of magnitude. I did not find better information and the real value should be found by someone else.

solar wind details inside :Properties and structure
Velocity and density :
“Near the Earth’s orbit at 1 astronomical unit (AU) the plasma flows at speeds ranging from 250 to 750 km/s (155–404 mi/s) with a density ranging between 3 and 10 particles per cubic centimeter and”…
