Sunday School

Agreed. I only climbed up here to freak out my Fitbit stairs counter. And its all dark up here too.

If it’s not Time by Pink Floyd, it’s not time.

That is a good Sunday afternoon question to ponder but does anyone really know what time it is……?

And, Reg, once the two week transmission arrived, precisely which time zone do you feel would apply?

Also time related, Robert, even a broken clock is right twice a day 🙂

They are gonna need all the thoughts and prayers they can get. Trump in his mind was just making a deal, I am sure. That is what he does. It is interesting that many US companies are realigning their supply chains away from China to avoid the tariffs. His strategy may actually be working.

Assuming sound could travel through space it would take almost 2 weeks to tell you the time but if I used a radio, only about 2 or 3 seconds, depending on the time of the year. I thought the climb itself would be more impressive!

What would happen if you were wearing that watch while climbing a ladder to the moon

I’ll be a lot more impressed if you could tell me what time it is on the moon when you get there.

This preying priest is another reason that the Catholic Church should be disbanded.

The watch, over time (T), is losing energy even if it is not functioning internally and so entropy is increasing even though the system is not doing any “work”. If it was functioning internally and was doing “work” it would reach a high entropy state a lot faster.

Some called him a militant atheist for that above quote. Others see it as him dealing with the realities of life.

I am correct?

Now I have another question. Does a wound-up watch that’s not moving internally (say from some malfunction) weigh more than an energy-spent watch? Without doing any math my first thought is “yes” it does weigh more because of the stored potential energy.

agreed…plus kinetic and even a bit of thermal energy.

Another result of Einstein’s theory of relativity: A wind-up watch that is stopped has less mass than the same watch that is ticking away.

I had an urge just last week to google whether or not an atom gains and loses mass whenever it absorbs and emits a massless photon. Sure enough, it does! Absorbing a photon causes an electron t…[Read more]

Thanks, Reg!

Christopher Hitchens

Ouch!

It is amazing that AI can now find solutions to the three-body problem in under two seconds.  It’s interesting that it learned how to do it from Brutus the brute-force program.

Have a great week everyone!!

“Our weapons are the ironic mind against the literal: the open mind against the credulous; the courageous pursuit of truth against the fearful and abject forces who would set limits to investigation (and who stupidly claim that we already have all the truth we need). Perhaps above all, we affirm life over the cults o…[Read more]

Here is a course on the scientific basis for morality (or at least, a plausible one) I have put together.  I know some of it could do with editing.

Basics of morality and ethics

• The Healing Principle
• Perfect Compassion
• Moral formulae of cooperation
• The Stakeholder Principle
• Cooperation
• Competition
• Fairness
• Reciprocity
• Targeted…
