The two most common elements in the Universe are Hydrogen and Stupidity.

- Jerusalem (Wikipedia)
Jerusalem (/dʒəˈruːsələmˌ -zə-/ jə-ROO-sə-ləm, -zə-; Hebrew: יְרוּשָׁלַיִם Yerushaláyim, pronounced [jeʁuʃaˈlajim]; Arabic: القُدس al-Quds, pronounced [al.quds], local pronunciation: [il.ʔuds]) is a city in the Southern Levant, on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is one of the oldest cities in the world, and is considered holy to the three major Abrahamic religions—Judaism, Christianity, and Islam. Both the State of Israel and Palestine claim Jerusalem as their capital. Israel maintains its primary governmental institutions there, and Palestine ultimately foresees it as its seat of power. Neither claim is widely recognized internationally.
- Chemical element (Wikipedia)
A chemical element is a chemical substance that cannot be broken down into other substances. The basic particle that constitutes a chemical element is the atom, and each chemical element is distinguished by the number of protons in the nuclei of its atoms, known as its atomic number. For example, oxygen has an atomic number of 8, meaning that each oxygen atom has 8 protons in its nucleus. This is in contrast to chemical compounds and mixtures, which contain atoms with more than one atomic number.
