The Fascinating World of Crystals: Formation, Growth, and Uses
TLDR Crystals are highly ordered structures that can be formed in various ways and found in different substances. They can take a long time to grow and have been appreciated for their beauty and believed to contain energy for thousands of years, although crystal healing is considered pseudoscience and should not be relied upon as a substitute for medical advice.
Timestamped Summary
00:00
Crystals are highly ordered structures that defy the tendency of the universe to move towards chaos and disorder.
05:29
Crystals can be formed in various ways and can be found in different substances, such as salt, snowflakes, semiconductors, and liquid crystals.
10:18
Crystals are formed when ions or atoms clump together and form a three-dimensional model, which can continue to attract more atoms and build upon itself, resulting in a lattice structure.
15:14
Crystals can form under ideal conditions, resulting in a single crystal, but more often they form as polycrystals, which are multiple crystals that have weak points where they join together.
20:05
Crystals can form from a solution by saturating the liquid with salt or other substances, causing the solid state to form and crystals to grow, and this can happen under different conditions and in various environments.
24:52
Crystal-pulling is a method of growing crystals using a seed crystal that is slowly raised out of a purified solution, and this technique can produce large, perfect crystals.
29:52
Chemical vapor deposition and liquid phase epitaxy are two methods used to grow crystals, with the former being faster and commonly used for synthetic diamonds, and the latter involving lifting a flat atomic substrate crystal out of a solution to form a crystal.
34:37
Gemstones are crystals that get their color from impurities, and crystals can form different shapes under different conditions, which people have appreciated for their beauty and believed to contain energy for thousands of years.
39:31
Crystals can take a very long time to grow, with some taking up to 10 million years to reach just two centimeters in size, and while crystal healing is often considered pseudoscience, it involves the use of different crystals to facilitate healing energy and channel out negative energy.
44:27
The effects of crystals on healing sessions are likely due to the placebo effect, and while crystal healing is generally considered harmless, it is important not to rely on crystals as a substitute for medical advice.
49:05
Diamonds, formed under tremendous temperature and pressure, will eventually melt into graphite over a long period of time.
