Technology & Information / Re: Mirrorless Camera

I rented one of these and holy shit, it has to be my favorite camera of all time. It has a little turd nugget of a sensor that isn't a great deal better than a cell phone camera, but it's tiny, lightweight, and has the best weather sealing and image stabilization on the market. The micro 4/3 sensor also has a 2x crop factor relative to a 35mm camera, so you'll be getting way more "reach" if you're into telephoto shots. The lenses are also very compact and light.

It's pretty expensive for having a turdlet sensor at $1000 for only the body, but you're getting features that are comparable to, or even better than a camera that's twice as much, all in a super compact frame. Beyond 400 ISO you start getting some pretty grainy shots. My R6 can handle up to 6400 ISO with minimal grain, but I still prefer using this little camera somehow.

The sensor isn't THAT small, it's only half the size of an APC-C sensor, still far bigger than anything you would find in a phone.

But it's a great format and camera.

As they say, the best camera is the one you have with you. These things are small enough to stuff in a pocket if you slip a pancake prime on them. A lot more convenient than a full size DSLR with a huge lens.

I say it's a turd sensor just because you can get a Canon RP for exactly the same price, which has a full frame sensor and will give you much higher quality images, all else being equal. But yeah, the fact that the Olympus is so tiny means you can take it pretty much anywhere like you said.

The Earth is like a Frisbee flying through space.  It tilts, spins, and wobbles.  Think of a gyroscope and its gentle rotation.  If it rotates once a year then you seasons remain intact.

I got the concept, but you didn't answer any of the questions. Chief among them, how do you not have all 4 seasons everyday everywhere on earth? Rotation causes your day/night cycle, your tilt/wobble, whatever it is, causes your seasons. Your 24 hour rotation would rotate all parts of the earth closer and further from the sun giving everyone 4 seasons in 24 hours. Get it?

Flat Earth Theory / Re: Looking for curvature is a fool's errand.

I guess you didn't read my post carefully enough.

I did.  From a high enough altitude you can certainly tell the difference between a disk and a sphere.  Disks don't cause things (boats, buildings, continents) to vanish below the horizon when you or they move.  Spheres do.

Which is why I said, "if you went high enough, the earth would take on relative basketball proportions and your depth perception would kick in".

The boat and building thing is a given. This was meant to address those who think curvature alone prove sphericalness.

It's hard to give a full answer without knowing more of the specifics, but as a general thought:

Tides are caused by the earth rotating through the 'bulge' of water pulled by the moon. The magnitude of the tidal changes (up and down) AND the current velocities generated are extremely closely linked to local basin bathymetry. The cross sectional area of the inlets in relation to the volume of water along the coast is a major determining factor.

Examples that are opposing would be the Florida coast, which is straight and in direct connection with deep water vs the Bay of Funday, which is a v-shaped trough that shallows progressively inland.  The constriction in the Bay of Funday is what gives rise to the huge ranges in sea level between high and low tide, and creates strong, fast-moving currents along tributary rivers in the region.

Hope that helps set you on the right path :)

Flat Earth Theory / Re: Antarctica Sun

Jack, can you explain how the Antarctic 24 hour sun is different than the well established phenomenon in the Arctic?

How has the Antarctic sun not been independently verified? There are live webcams, accounts from thousands of scientists, and terabytes of satellite imagery to work with. Some data can be found in the links in my signature, and other testimony was provided in the ice wall thread I started in the FE Theory board

Lol, I had a few threads about this, but in short, it tilts towards the sun so it's centered above the equator.  It then wobbles slowly back and forth every year to give you change of seasons.  It also spins once every 24 hours but nobody likes that idea, lol.

Ok, well good luck with all that. From what I've seen across the wider than just here FE community, putting the earth in any sort of motion is lunacy. And if you even mentioned to those folks that it "rotates", my goodness, they would come after you with pitchforks and torches. Hyperbole, of course, but yeah, they don't take too kindly to an in motion earth of any kind.

What causes it to wobble and spin? How often does it wobble?

And you have a problem with your "idea". If it wobbles (tilts) periodically and spins every 24 hours, everyone on the planet would experience all four season everyday. That would be something, wouldn't it? Snow in the wee hours, flowers bloom in the morning, Summer heat in the afternoon, leaves tuning brown in the evening.

Flat Earth Investigations / Tidal Bores
« Last post by crwilson12 on March 02, 2021, 12:10:48 AM »
Hello in my area when the tide comes into the bay it creates a tidal bore which travels up a river that emptys into the bay.  It travels over 17 km in less than 45 minutes.  Going by earths curvature it has a massive amount of ground to climb as well as the brooks natural decline.  So how if tides come in so slowly takes over 8 hours here how does this tidal bore gain like 9m of height or more to travel that far up river,  when the whole time the wave stays almost exactly 2 feet tall for the entire 45 minutes

If you were on a raft in the middle of a perfectly calm ocean, and spun around to view all 360 degrees, it would all look exactly the same. It would be like being in the middle of a large hoop that arcs around you at a constant distance and then attaches back to itself after describing a perfect circle. There would be exactly zero appearance of curvature in the dimension that would prove sphericalness. You can't see the 3rd dimension you're looking for because you can't see past a horizon that is equidistant from you at all times.

I hate to bring up the boring sinking ship effect, but that would show the difference between being on a flat plane or circle, and being on a globe.  It wouldn't sink on a flat Earth.

The other effect is altitude letting you see further.  On a flat Earth, climbing up and down the mast of a ship wouldn't cause other ships to sink hull first into the water, but would on a flat earth.

There are a large number of visual effects you get on a sphere that you would not on a disk, and those allow you to indeed see the difference.

Correct. My point is that looking for curvature is one of the go-to methods, but it shouldn't be.

I'm not sure I know anyone who thinks standing at sea level and looking for curvature is a go-to method for showing the Earth is round.   

Looking for it at 30,000 feet, sure.  Or 400 miles up on the ISS, of course.  Or from a million miles out it's pretty clear.  I just don't see many people arguing you can see an actual curve from the ground, so I wouldn't call it a go-to method at all.

I guess you didn't read my post carefully enough.
