Titanium
- reactive metal
- first discovered by British amateur mineralogist William Gregor in black sparkly sand in 1791 , named it with manaccanite
- German chemist Martin Klaproth rediscovered in 1795 when analyzing rutile
from Hungary and named it with titan-ium
- "It was later determined that menachanite and titanium were the same element"
- the pure titanium (99.9%) was not isolated until 1910 by Matthew Hunter by heating TiCl4 with sodium in a steel bomb.
- Titanium is present in meteorites and in the sun.
- the ninth most abundant in the crust of the Earth.
- the only element that burns in nitrogen.
- Titanium is as strong as steel, but 45% lighter. It is 60% heavier than aluminum, but twice as strong.
- resistance to salt water
Titanium Anodization
This is achieved by controlling the thickness of the TiO2 (Titanium Dioxide) layer formed on the surface (interferes with light waves and produces different colors due to thin-film interference).
- TiO2: has an extremely high index of refraction with an optical dispersion higher than diamond; Star sapphires and rubies exhibit their asterism as a result of the presence of TiO2.

>in 1897 he made the first ascent of the Mönch without a guide
>In 1902, he was joined in India by Eckenstein and several other mountaineers: Guy Knowles, H. Pfannl, V. Wesseley, and Jules Jacot-Guillarmod. Together, the Eckenstein-Crowley expedition attempted K2, which was never climbed before. On the journey, Crowley was afflicted with influenza, malaria, and snow blindness, and other expedition members were also struck with illness. They reached an altitude of 20,000 feet (6,100 m) before turning back.
Interesting facts about Aleister Crowley
>in 1894 climbed Beachy Head before visiting the Alps and joining the Scottish Mountaineering Club. The following year he returned to the Bernese Alps, climbing the Eiger, Trift, Jungfrau, Mönch, and Wetterhorn.>in 1897 he made the first ascent of the Mönch without a guide

It was because I found Hans A. Traber's birdsong recordings on Tudor:
- 4 volumes of How Our Birds Sing released by Tudor (download: https://deep-swarm.xyz/share/music/Hans%20A.%20Traber/, download one folder by one folder, don't download four folders at one time)

really excited then made this simple tool, so far it's very useful for my current focus.

Climbing: Mountaineering, Rock climbing (especially free climbing), Mountain biking
Others: Hiking etc.
I am speaking of the nature of these sports not the current state of focus of sports events. Even if I doing road biking I don't follow road cycling race-events.
It is very interesting to notice that I always prefer "climbing" activities rather than "racing". Evola thinks that mountain-related sports could be categorized as ascending and descending, but this makes it tough to proper classify rock climbing, which are almost vertical, under the category of ascending. I think rock climbing and diving seem to be opposite-direction activities. However, rock climbing cannot be classified as ascending, and diving cannot be classified as descending. It just feels like this.
Another observation is climbing activities are spiritual in its nature. Up to now, rock climbing is the most purely spiritual sport. One reason is when it is the case of free climbing, the equipment you rely on is minimal and you make most use of your body and mind. Another reason is that the process of rock climbing has a more subtle randomness and is confined to an almost two-dimensional plane with extremely small cracks exist which you would be highly dependent on. This is also where you make the body moving with wonderful rhythm.
