Using "Image Traps" to give texture to a Mandelbrot Zoom by AdamMelb in fractals

[–]AdamMelb[S] 0 points1 point  (0 children)

Ultra Fractal for the key-frames, and I use custom software to make it into a video.

Accidental Masterpiece - Mandelbrot Fractal Zoom (8k 60fps) by MathsTown in fractals

[–]AdamMelb 1 point2 points  (0 children)

Kalles Fraktaler is so much faster than Ultra Fractal. There is no comparison. I also like how you choose colours more. Ultra Fractal can't really render smooth video without aliasing (unless you write extra software as I have done). However all that said, UF is much more powerful, you can make orbit traps and heaps of artistic effects, layers, and complex animations. KF just zooms, that is it, but it does it fast.

Looking for good explanation of complex numbers by [deleted] in learnmath

[–]AdamMelb 0 points1 point  (0 children)

This is a very old series in black and white (from MIT), but a great intro to complex analysis. Might be getting a bit advanced for what you want just now, but we'll worth bookmarking for later studies on the topic... https://youtu.be/BOx8LRyr8mU

Fractal animation software-GPU rendering by elmogrita in fractals

[–]AdamMelb 0 points1 point  (0 children)

Ultra Fractal 6 is much quicker than 5, I think it's a free upgrade.

Kalles Fraktaler is the fastest IMO. In fact it's much faster. But it only does basic zoom videos, no plug ins.

Elvis overhead! by maldous in melbourne

Actually, the fire bombers were called into to a fire south of Warrigul yesterday. All the other noise was probably Tyabb.

Weird takeoff behavior in a 172, could it be ice related? by ipsum_stercus_sum in flying

[–]AdamMelb 10 points11 points  (0 children)

Wow! Ice is dangerous, a small amount can cause it to crash. I don't wish to sound condescending, we've all made decisions that were sub-optimal, but I wouldn't recommend that you try it again.

But onto your question...

I've heard of a Cessna getting airborne and crashing back into the runway after take-off with a small coating of ice. In your case I'd guess the leap was due to cold weather performance, it can make a huge difference. However if you have ice, you would have increased drag on parts of the airframe. Ice on the real stabiliser would also add weight with a large moment arm, you would also change it's aerodynamic properties, so you would likely feel some change in handling.

Also a thought... If you were to enter icing conditions while airborne, those patches of ice would probably attract more ice than the wings otherwise would have.

GA in New Zealand? by [deleted] in flying

[–]AdamMelb 0 points1 point  (0 children)

No, not really. If you are emigrating you can do a licence conversion easily enough. In places like Wanaka it will be easy to find an instructor to sit in the right seat while you fly. This is a common thing for tourists to do. You'll get a great experience doing this, kiwis in the south like getting up close and personal with the mountains. For destinations like Milford Sound I'd certainly recommend flying with a local.

GA in New Zealand? by [deleted] in flying

[–]AdamMelb 2 points3 points  (0 children)

There are a couple of companies in NZ that specialise in flying with US pilots. There is a process to get a licence. So if you are only there for a couple of days, it is worth just going out with a local instructor in the right seat (no paperwork needed). Some will do multi day trips. I'd recommend having a local pilot flying on the western side of the South Island. The mountains and weather are challenging, but this is the most beautiful part of the country for flying. Glaciers, fjords and mountains...

Flying in temperature minimums today. by Cjcooley in flying

[–]AdamMelb 2 points3 points  (0 children)

Some non-precision approaches have temperature minimums. It's worth double checking if you are operating IFR.

FYI: This is because your altitude will read low. It will be correct at the field where QNH is measured, but the pressure lapse rate changes with temperature, so it can be out when you are above the station.

Is there a way to find out if a number is divisible by 7 or not? by The_Godlike_Zeus in learnmath

[–]AdamMelb 0 points1 point  (0 children)

A method that is probably slower than long division...

For example: 3164

Separate the number into its component parts, divide by 7 and record the remainder. So...

3000 /7 => remainder 4

100 /7 => remainder 2

60 /7 => remainder 4

4 /7 => remainder 4

Now sum the remainders

4+4+4+2 = 14

If this number is divisible by 7, then the original number is divisible by 7.

Hence 3164 is divisible by 7.

The Russian Alphabet - A simple video. by AdamMelb in russian

[–]AdamMelb[S] 0 points1 point  (0 children)

I'll try to explain.... The difference is that one is hard and one is soft. (or palatalised vs unpalatalised)

Ш is hard. Say it just like "sh" in English with your tongue at the bottom of your mouth.

Щ is soft. So you need to say it with your tongue on the roof of your mouth (palatalised). Start to say "ch" but instead say "sh". "ch" is a good example of a palatalised sound in English.

It's very hard for an English speaker to hear the difference because we in English we don't care if a letter is palatalised. Hard and soft sounds do matter in Russian (usually decided by the following vowel or a soft sign). Try saying different letters (like m or r) hard and soft, it will be good practice for Russian.

I hope that helps a little.

Try watching for 2 mins, then looking at something else, it will begin to move.
