The characteristics of an atom
By: Joe Barrette
The atom is the most basic unit of matter, it is the building block of the world we live in. Every element has it's own unique type of atoms. The atoms are composed of a nucleus surrounded by dense clouds of orbitals containing electrons, which...

Take a Break from Time by Immersing yourself in the Present Moment
By: Seth Greenwald
Time is simply a construct of the mind. It's only when we use the faculty of memory does time arise. What would it feel like to keep your consciousness in the present moment? Time would just drop away. We would experience the ever-changing "now" moment...
Do you believe that aliens have already visited our planet?
By: David Brown - 226423
Not have aliens already visited our planet in one form or another, but they continue to visit our planet today. We can look at some evidence of early visits of aliens, and then we can look at visits over time until present day visitations. Not...
The basics of covalent bonds in molecules
By: Lime Red Tetrahedron
Covalent bonding is a form of intramolecular bonding that occurs as a result of a sharing of electrons between atoms, usually occuring between elements of similar electronegativity. Electrons alternate between two or more atoms, causing the atoms to attract. This bond imparts certain key characteristics...

Just to avoid any confusion up front, you cannot plant a seed crystal in the ground and grow a lovely crystal tree. It'd make for great reading, but I'm afraid it's quite unrealistic. A seed crystal is used to grow larger crystals, but only when...
