[Q]: These American billionaires also share a few quirks: Microsoft founder Bill Gates  Facebook CEO Mark Zuckerberg   Oracle founder Larry Ellison  dropped out of college. Jeff Bezos  Larry Page and Sergey Brin all went to Montessori schools  where children are encouraged to think independently and creatively rather than following traditional rules. It seems  too  that billionaires really like houses in Hawaii.
As is the case with the richest women in America  the richest people in America donate a lot of money to causes they care about. Some of the men on this list have donated hundreds of millions into research designed to improve human lifespan and eradicate dangerous diseases  such as Alzheimerâs disease and cancer. Warren Buffett  Gates  Zuckerberg  and  Ellison  have gone a step further and promised to give their fortunes away as part of The Giving Pledge  an initiative designed by Buffett and Gates to encourage billionaires to funnel their vast wealth to philanthropy.

 Ellison   73 â another college dropout â co-founded the software firm Oracle in 1977. In addition to owning about 25% of the company  he also owns the entire Hawaiian island of Lanai  a sailing team and even an entire tennis tournament  the New York Times reports.
While known for living large (the billionaire owns a 288-foot yatch)   Ellison  started out with modest ambitions.  His  parents  who adopted  him  when  he  was nine months old  wanted  him  to be a doctor  but  he  left school when  he  realized medicine didnât interest  him .  He  moved to California and worked as a computer programmer and a rock-climbing instructor and river guide  according to the Times. At this point   Ellison  said  he  was âpretty happy with  his  life.â
But after a series of jobs   he  became part of a company working to establish a new type of software database. That company would become Oracle  now one of the largest software companies in the world.
 Ellison   like other titans on this list  is interested in extending human lifespan  and has given over $330 million for research into aging and related diseases.
Four-times divorced   Ellison  has two adult children and calls  his  $70 million Woodside  Calif. estate home. However   Ellison âs massive real estate portfolio means  he  never spends much time in one place.  He  owns additional properties in Japan  San Francisco  Malibu  Lake Tahoe and Rhode Island.

[Q]: Stephen Paddock  fired hundreds of rounds out of a 32nd story window in the Mandalay Bay Resort and Casino on Sunday night  police have said  killing 59 and injuring over 500 in the deadliest mass shooting in recent US history.
 Paddock  had no military training. According to Paddockâs family and the ongoing police investigation   he  had a penchant for guns and some experience hunting. But there is no indication  he  had formal training.
Nevertheless   he  managed to kill dozens and wound hundreds from 32 stories above the ground and a distance of three to five football fields between  him  and  his  victims.
The reason  he  was able to carry out the massacre lies largely with the tools at  his  disposal and the completely helpless nature of  his  targets.
Some of the weapons had scopes to increase  his  effective range. The length of the bursts of fire suggest  Paddock  likely used extended magazines to store many times a firearmâs normal capacity in ammunition.
All of Paddockâs guns legally belonged to him. Nevada  where  Paddock  lived  allows the sale of high-capacity magazines  high-caliber weapons and ammunition  and military-style weapons  but it doesnât allow fully automatic weapons.
 Paddock  got around the limitation of government-mandated semi-automatic weapons by using something called a âbump stock â which effectively turns a semi-automatic rifle into an automatic  according to The Associated Press.
From 300 to 500 yards away  the crowd of 22 000 were essentially âfish in the barrel â which is how country singer Jake Owens  who was on stage in Las Vegas  described that night. It wouldnât take a military operative or master marksman to inflict grievous damage on a crowd with the tools  Paddock  had available.
 Paddock  simply rained down bullets on an unsuspecting crowd that was focused on the stage. Because bullets from high-powered rifles travel at supersonic speeds  the first shots probably hit the victims before the sound of the rifle even rang out.

[Q]: Story highlights  Romualdo Pacheco  was the first Hispanic governor of California
 Pacheco  also served in the US House and as a diplomat
 He  reportedly lassoed a grizzly bear  as one does
(CNN)  Romualdo Pacheco  was not only the first Hispanic governor of California  the 19th century politician was also the state's only Hispanic governor to date. Not to be outdone by  himself    Pacheco  was also the first Hispanic member of the House with full voting rights.
 Pacheco  was born in Santa Barbara  California  when the land was still held by Mexico .  He  was born to a prominent family and -- living  his  best life from a very young age -- was sent to Hawaii for school and had to re-learn Spanish upon  his  return home.
 He  grew up to be the fierce gentleman you see in the Instagram photo above. You will not be surprised to hear that  man  worked as a sailor  a miner and a rancher. Multiple sources credit  him  -- in an oddly specific way -- as being the only California governor known to have lassoed a grizzly bear. That implies that other California governors have run around roping grizzlies and not told everyone they've ever met. Regardless  that's pretty hardcore.
 Pacheco  became an American citizen in 1848 and got to work as a public servant .  He  began as a judge for San Luis Obispo Superior Court before serving as a state senator beginning in 1857.  He  did time in three parties  starting as a Democrat  then becoming a member of the Union Party before settling down as a Republican in 1863.
 He  continued checking off important state-level positions  serving as the state treasurer and lieutenant governor. When Gov. Newton Booth left to serve in the US Senate  Pacheco took over  serving as governor from February-December 1875.
