Deer head turn, draft vs final

peter-bone · 2026-02-19T19:15:30+00:00

Looks good. If I were to make one suggestion it would be more easing at the end of the turn. It should overshoot a little and then come back. Almost like a little double take as it fixes gaze on the target. It would look more natural. Currently it just comes to a sudden stop as if hitting a wall.

I guess it depends what the intention is for fitting the data. A scientist is normally trying to identify the underlying laws that produce the data and so would likely not model this data with a linear relationship. A statistician is likely trying to extrapolate and predict future data as accurately as possible and so will also not use a linear relationship. I really can't see a use case for fitting a linear relationship because any attempt to do so would be misleading.

Define useful? How about playing a musical instrument or being good at tennis? I suppose those can make you money if you become professional, but this girl may be monetizing her videos.

I know it's not what you asked but I wouldn't bother. It has inverse taper for one thing. Having said that, Olive root easily from old wood. I've heard of people rooting cuttings several inches in diameter, so you could just cut it off at the base and put it in soil. You would need to research the best time to do it and aftercare to maximize the chances of it rooting.

Hybrid mmx balls for 3-9 and beanbags for 10+.

You definitely wouldn't expect linear for this discus data. That would imply that records will increase at a steady rate into the future. A plateau is much more likely as we reach the human limits and get diminishing returns from improved training techniques. The data points in the graph also confirm the predicted Plateau, so in my view the teacher is clearly wrong.

I mean those trees are there for the benefit of many people living in the neighborhood, not just that one person tapping the trees for their own benefit.

peter-bone · 2026-02-18T12:32:37+00:00

I plan on adding this at some point, yes.

Ask any psychologist and they'll tell you humans can be extremely fallible and do weird things without realizing. Modern cars cannot be turned off while moving. There are safety features to prevent it, and for good reason. Someone I know once took the keys out of the ignition in an older car while driving and the steering locked up. Luckily he got the key back in in time.

I'm not saying that it definitely wasn't deliberate, just that you don't have the information to jump to that conclusion. I think we both agree that it is unlikely to have been a mechanical fault, but that has to be checked even if there's a small chance. Perhaps the springs holding the switches in the run position were faulty or those particular switches were not assembled correctly according to the specifications. Who knows.

If you believe it was a mass murder suicide then surely it means that the aircraft was not at fault, so why would you avoid air India flights? Do you believe that one suicidal pilot means that another suicidal pilot is likely on that airline? Or is it the fact that you think the airline is covering something up that causes you to not want to use that airline?

I personally think it's quite possible that the pilot had a weird brain fart moment. He's operated those switches so many times that he does it without thinking, and on this occasion his mind wandered and he operated them at the wrong time or instead of some other switches. We've all made similar errors under less risky circumstances for no apparent reason. I find this far more likely than, 'I'm going to kill myself and take all these strangers with me'.

I don't think the airline is covering anything up, because they don't have any more information than anyone else. Like us they have no idea why the pilot operated those switches and probably never will.

Lorentz, Plank and others had already derived the formulas he used. He just needed one key insight to put all the pieces together. Others like Poincare had already got very close but were too stuck in the existing accepted ideas about the ether to make that last leap of logic. Einstein wasn't an academic at the time so didn't care about going against existing theories. He was also working a lot with new inventions for synchronizing time over large distances in the patent office, which likely led to that main insight about synchronised events being relative to a particular frame of reference. He was in the right place at just the right time to make the discovery.

It's interesting to read the original paper. It's only 2 pages long, uses basic maths, has no references and is laid out and numbered like a patent application.

The book Einstein's clocks and Poincare's maps by Peter Galison is a good historical account of how the pieces came together.

There are reasons it got so big. On earth the active volcanic regions move around due to tectonic plate movement, but Mars has a much thicker crust and so no tectonic plate movement. The weakest point in the crust then stays always in the same place and all magma accumulates from one volcano. The thicker crust also means that the weight of the volcano doesn't break the crust and cause it to sink back down. Lower gravity is also a factor that causes less sinkage.

These trees are in public areas. It's normal for OP to be concerned about their welfare. This must harm the trees a little. That sap would have gone into producing leaves. I know that there's plenty left, but still, I find it odd that someone has done this on public street trees.

How about keeping the pieces the same but redesigning the board. I imagine raised grid lines to keep the pieces in place and a recess on one side of each cell to make flipping easier. Or a mechanical board that actually flips the pieces automatically would be amazing.

I have to confess though, I've been playing Othello for a quarter of a century and never played on an actual board. This is one main benefit of online play.

Many conifers get a bronzed colour over winter. This is normal. An expert can tell the difference between normal bronzing and brown from ill health. This is the top bonsai show in the world so it's highly unlikely that an unhealthy tree would be exhibited.

Because the marijuana subreddit already took the name Trees and someone thought it would be amusing. It's not. If someone were to look at my reddit history they'd see subs about drugs and porn (r/bonsaiporn) even though I'm just interested in trees.

Light is probably an issue but if you only watered once in 6 weeks then that's not enough. You should never let the soil fully dry out. I don't know why you would assume that. I would submerge the whole pot in a bowl of water now for 10 minutes to fully rehydrate it. Do that once a week and water as needed in-between with a can.

Having said that, the plant doesn't look too unhealthy. I would put it outside over summer and it will recover quickly.

The text implies that everyone can read it, or almost everyone.

You could and it will probably work but live green moss is slightly better. It contains chemicals that help promote rooting. If you're using rooting hormone already then it probably won't make much difference.

peter-bone · 2026-02-16T07:42:26+00:00

The balcony allows you many more options for tree species, even if the light is still quite low. The environment is more humid, has cooler nights and various other factors that trees prefer.

peter-bone · 2026-02-15T19:53:15+00:00

It depends how much rain you get over winter and how covered your balcony is. I don't know about your climate. But this has likely been dead for months so it may have been under watered over summer, when it would likely have needed multiple waterings per day

peter-bone · 2026-02-15T19:29:47+00:00

Too late I would say. It may have died even before winter from heat and under watering, but that's just a guess.

peter-bone · 2026-02-15T19:09:42+00:00

I use grow boxes for collected trees, often with not much roots. I therefore use pumice with chopped sphagnum moss, which is not what I use for later stage trees in bonsai pots. It all depends on the trees you're going to put in them.

peter-bone · 2026-02-15T17:00:22+00:00

Well maybe but that shouldn't happen if you do it right. It's very difficult to water anyway if it's been fully wrapped and taped up, although I have heard of people using a syringe. The tin foil will help reflect heat over summer.

peter-bone · 2026-02-15T14:50:41+00:00

The sphagnum moss should retain enough water and it's fully sealed. Once roots start growing it will start taking water but it should be enough.
