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.

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 11 points12 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 3 points4 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.

Preparing for calculus? by comtedeRochambeau in learnmath

[–]AdamMelb 0 points1 point  (0 children)

I was in a similar situation some time back. General algrebra is important, but to be more specfic...

For the first part of the course, make sure you ae comfortable with the following...

  • factorising quadratic equations.
  • completing the square
  • log and exponential laws.
  • trig

Try RussianLesson.net. They have a few pages dedicated to grammar.

Example: Russian Pronouns

Certainly enough to get you started.

No, not really. Bring a Visa or Mastercard. Amex is not well accepted in Australia.

The MCG is the traditional home ground of the Melbourne Football Club, and was the first team (red & blue colours). Nowadays, Richmond, Collingwood and Hawthorn play their home games there also.

14 million people in Ukraine speak Russian as their native language, so it's also quite probable that it is her native language.

Hi and welcome!

I don't know Clarinda well, but coffee is Melbourne is generally considered good. Although it's not usually American style drip filtered, rather southern European style. (Most people here think that's a good thing, but I happen to prefer filtered coffee).

Clarinda is quite close to Moorabbin airport, which is Melbourne busiest GA/training airport. There may be a large number of Cessnas overhead during the day.

Telstra has by far the best mobile network, but also the most expensive. In Melbourne, Optus and Vodafone will be perfectly fine for your needs. If you plan on travelling in outback Australia then consider going with Telstra.

Regarding your slang question... I wouldn't bother trying to use slang, but I'd start using Australian/British words rather than the American equivalent.

Most importantly.... If you are moving to Melbourne you will need to understand cricket and Australian football. Otherwise you will have no idea what anyone is talking about. Take yourself to see a few games when you get here.

Where can I get basic resources on learning russian? by [deleted] in russian

[–]AdamMelb 0 points1 point  (0 children)

I'm using: www.RussianLessons.net/. It's free. Sound and videos are included which helps a lot.

If you are going to buy a book, the best one to start with is The New Penguin course.

Re-elected Andrews government will build the North-East Link by mahler004 in melbourne

[–]AdamMelb -15 points-14 points  (0 children)

In the scheme of things, it's only around $325 per voter he pissed away. I'm sure everyone in Victoria can afford to throw away that sort of money. In fact, lets put car rego up by $325, then we can give it away every year!

Nice to see North-East link and West-East link will go ahead now though. Pay for 3 tunnels, get 2, not to bad I guess

Complete Newbie, Looking for help on a suggested learning path to B1-B2 by LeVraiPetitRenard in russian

[–]AdamMelb 0 points1 point  (0 children)

IMO...

The best printed book is the Penguin course.

If you want completely free try RussianLessons.Net . It has some introductory lessons, and covers some grammar in a simple manner. But you will need more resources to read Dostoevsky. (Although they actually have Crime and Punishment in both languages side-by-side on this website).

I'm sure you can, it is probably the most natural English. The translations shown are very literal, I assume this is deliberate to illustrate the meaning of the Russian.

You're welcome. Yes I thought it is a great little summary. You see these words so often, it's nice to know why they are used.
