I will not stand for this Planck erasure! Sure, Einstein and Maxwell are great, but how can you leave off the father of quantum mechanics when a third of the poster is a direct result of his research?
As a non-sciencey person, can someone explain the chasm of ignorance?
Most of the "chasm of ignorance" is the stuff we know that we don't know. We don't know what dark matter is made of. We don't know what dark energy is. We don't know how to reconcile quantum mechanics and general relativity.
I’m not a physicist, but im pretty sure it’s just the gaps in our knowledge like exactly how/why gravity works. And like we don’t know the things we don’t know so it’s all in the chasm.
I've had this poster in class!
Isaac Newton — 'To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me'
Dark matter is just the friends we made along the way.
Who would win? All the physicists or one slitty boi?
Cosmology and astrophysics are considered classical? I would expect both quantum physics and relativity to play a major role nowadays.
At least cosmology does use some serious quantum physics, even quantum field theory. Source: took 1 year of theoretical cosmology lectures.
damn you doing philosophy dirty
We have this on the wall in my physics class
Naïve question: Is there a reason why electric and magnetic fields look so similar?
edit: in assuming it's something to do with direction / polarity?
They're similar in some respects, different in others; this happens to only show ways they're similar. Specifically, it only shows dipole (two-pole) fields, with the field lines running from one pole (North or +) to the other (South or -).
But there are also electric monopoles: things that're only + (e.g. protons) or - (e.g. electrons), which'll have field lines radiating out in all directions rather than looping back. Magnets are different in that as far as we know, magnetic monopoles don't exist. Every North pole's directly attached to a South pole and vice versa. You can get magnets with more than two poles, or even more complex arrangements (e.g. refrigerator magnets normally have alternating North and South stripes), but they'll always have equal amounts of Northness and Southness, so the net magnetic charge is always zero.
Another (related) difference is that moving electric charges (e.g. electric currents in a wire) create loops of magnetic field. That is, the field line just goes in a circle around the moving charge, rather than from N to S. Since there's no such thing (as far as we know) as a magnetic charge, that can't happen with the electric field.
Wow, that's really interesting - thanks!
Naïve answer: A magnetic field is an electric field moving through time. There's some matric math that equates moving electric charges to magnetic force, I think Maxwell's equations? So it's kind of about direction, but through time.
Science has always been wrong, converging towards the truth. The scientific method is based on this. It is not the first, nor the last time, that a scientist has to throw years or even centuries of research into the trash, silently retiring in tears. Precisely now with the discoveries of Jame Webb it is becoming increasingly evident that the standard model, the BigBang as understood until now and the expansion, among other things, are no longer valid as such..
Very cool poster, thanks!
