> You can contest facts, he said, but not images.

with the ubiquity of photo editing, and ai driven video manipulation, i'd argue one can contest images too(i):

there are a couple definitions you would need to elaborate on to realise this question fully

by particle physicists usually mean any electromagnetic phenomena that seems to have distinct energy levels and so can refer to any number of things depending on context: photons, electrons, protons, atoms(o)

as for interact, what do you mean by this? would you consider entanglement an 'interaction'? the idea of a wavefunction is basically that every particle is 'interacting' with every other particle in existence in every direction with potential of collisions being discernible by the probabilities of the particle's position being spread out ad inifinitum

according to relativity light has a constant speed, meaning it is always moving at 'c'

since the photon is moving it has energy and though it has a 'rest' mass of 0 it is without a rest frame because it is always moving at that constant speed and so always has some measurable mass

because of this even in a universe with only a single photon without anything to interact with the photon would still affect spacetime

if you remove the 'only' from your question then the answer is an emphatic yes because you yourself are a collection of 'particles' 'interacting' and you are affecting spacetime

> by particle physicists usually mean .. photons, electrons, protons, atoms(o)

I meant pretty much anything that can be described by wave function evolving according to Schrodinger equation.

> as for interact, what do you mean by this?

Exchange of energy through any of 3 physical forces (not gravity). So not entanglement.

Single photon universe would never be observed so it would have wave function but never have specific location so according to my idea it would not affect spacetime.


i built something similar for a home project

i ended up taking it down due to concern of having all of that weight above me

when a huge mass is suspended above you the potential gravitational energy becomes very palapable


if you like pepper i would recommend trying the green variety, it is delicious and rarely in peoples spice cabinet


seems logical.. i would argue the inflection point in the ubiquity of pooled compute services came as bandwidth needs increased due to more businesses interacting directly, remotely and in real time, with customers, be they consumers or other businesses

if compute needs were all internal, as they are with desktop apps.. namely, compilation.., and with the majority of computationally expensive machine learning demands.. namely, training.. then i'd argue the pooled compute model would have remained niche


even more mystic in its infancy when it was an abbreviated phone number you would call, hold up the phone mic near the source, get hung up on and then recieve a txt with your song title and artist.. in 2002

> The description that General Relativity puts forth ... needs to be augmented to include an uncertain position that has a probability distribution to it.

i am sorry but 'needs' is too strong here

quantisation(o) was established before, necessarily so, probability was introduced to explain the behaviour of electromagnetic phenomena

to claim that probability is necessary for quantisation seems to have it reversed

the current understanding is both unknown whether gravity is quantised but also whether probability is necessary to describe quantum behaviour

with current understanding the only thing one can say with certainty is that requiring probability is a result of the math used to best model quantum behaviour of electromagnetic phenomena, namely fourier analysis(i)

i learned to surf as an adult

it can be a supernatural feeling.. paddling hard until the moment the wave picks you up and says, 'i got you from here' and just carries you off

when picking a board you should know the bigger the board the more stable it will be and the more forgiving it will be as you stand up, ~40-60cm taller than yourself is a good rough metric for a medium sized board, you can start bigger and as you get better try smaller and smaller boards

i have been body surfing and boogie boarding since i was a kid so, unfortunately, i am unable to give you any good tips on picking a good wave and figuring out the timing, but i think this may be a skill that can develop on its own with time

as for the surf.. the best advice i can give:

1) when waiting for a wave: stay on your board; the more time you spend on the board the more intimately you will get to know it and the more you will develop your stabilizing muscles and core

2) when paddling for a wave: arch your back as much as you can to lift your chest off the board; it will look like the 'bhujangasana'(o), or 'cobra', yoga pose and this helps to keep the board level in the water and allows for more strength in your paddles

3) when standing up: look down at the board to ensure you place your feet in the center; early on i had the tendency to look up at the shoreline and would place a foot a bit off center and the board would flip

4) when standing up: bend your knee and plant your back foot first; early on it was more natural for me to plant my front foot first but bending your knee and planting your back first ensures your center of mass is directly above your foot

5) once stood up: keep your knees bent; this keeps your leg muscles activated allowing for better balance and control

of course, most important: have fun!
