Human barbarism is not new... "The placard recorded that the Nooksack tree produced 96,345 board feet (227.348 cubic meters) of the "finest quality" lumber. The New York Times regarded the tree in a March 7, 1897 issue as the "most magnificent fir tree ever beheld by human eyes" and called its destruction a "truly pitiable tale" and a "crime". The Morning Times of February 28, 1897 claimed that the wood, sawed into o…

> Human barbarism is not new... to be fair, without humans there would be nobody to declare "barbarism". At one time, all humans were barbarians, it took a certain level of cultural development before the word "barbarism" was necessary, so at that point it was "new". It remains be be shown whether cultures that call other cultures "barbaric" are actually "better".

This is such a useless comment. What even is your point?

I grow marijuana and chillies from time to time. I got good at it. I will say that plants are malleable in untold ways and so I find this article to be unsurprising. Plants will do what they need to do in the end. I've done stuff like co2 bombing, and increasing nutrients to the point to where I get a whole new ecosystem of insects and an entirely new situation. It is such fascinating stuff that it's actually the lif…

Have you considered computational biology? They are always looking for people. Knuth said a while back that biology has tons of open and useful problems left to be solved.

I'm studying for a bachelor's degree in horticulture part-time through a distance-learning university. If you're more interested in growing plants, I'd say horticulture is a better fit than botany. If you're more interested in understanding how plants work, botany is probably the better choice. That said, you'll still learn a lot of botany in a horticulture degree as well obviously

With a lot of software getting eaten up I’m increasingly interested in biology. Seems like one of the later frontiers that could have massive benefits, and AI is really well suited to help us understand it.

True and also, the actual physical contact and results are absolute magic. Maybe we need to create a "computer scientists for botony" forum. I think that has legs. Botany is great because the results are basically what I'd call magic. It's such beauty (and horror on occasion). The marriage of CS and botany seems like a match made in heaven and just from writing these comments I've convinced myself that it's probably…

Just about everything we experience in our lives is a constant distraction from the fact that biology and its mechanisms are the most interesting thing in our existence.

Absolutely this.

There are obviously other factors limiting tree growth, like compressive strength.

I seem to recall for some long-ago course that the 8,000m peaks are up around the compresssive limit so yoou couldn't really have a taller mountain.

Mostly true on Earth, but not on other planets with lower gravity, and AFAIK it depends on the rock type. Hence why you have Olympus Mons on Mars (or insanely tall ice mountains on Pluto, when that material couldn't form such a steep talus angle on Earth).

Thank you sir. I actually got my CS from distance learning and somehow the combination of growing things and monitoring everything using CS just grabs me. I would work on any farm anywhere with appropriate agency.

>Giant trees have no trouble pumping water to top branches Hm, may be because they are not really "pumping" the water?

What would you call it?

They do wave in the wind, and evolution is likely capturing some of that motion for work.

Not sure if you’ve ever visited the groves in California where these huge trees grow but they seem to find the place where the wind doesn’t really seem to bother them, among other reasons (fog staying and little creeks terminating are others). And when the wind comes along it’s surprising how little they actually wave. Such tiny radii change I reckon cannot move much water like you’d need for a pumping notion. So I’d say it has barely if any an influence

The largest tree on record is rejected in part because it's over the theoretical limit: https://en.wikipedia.org/wiki/Nooksack_Giant Too bad we cut it down, along with almost every other giant Douglas-fir.

I just visited this beauty[1] a few weeks ago. Not 400ft tall, but over half that and over 13ft round at the base!

We're lucky to have a handful of big Doug Firs, Sitka Spruce, and Western Red Cedars left on Vancouver Island.
