10 Hackers Who Drastically Changed the World (Reblog)

#1 is Julian Assange ... #10 is Anonymous

"Yes, literally. While hacking is as amoral as science or mathematics, and therefore couldn't possibly be morally wrong, it is indeed literally wrong. Hacking, in the broadest sense of the word, is to attempt to interact with a system (any system) in a clever, innovative, and challenging way that the system was not intended to be interacted with, or the wrong way."

Women in Science : Give Credit When Due

Celebrating Women's History Month.


There's a scripture that says we should "give credit where credit is due, and give honor to whom honor is due".  Don't know why, but it's easy to laud this principle and very difficult to apply it to real life situations. Anyway ... I don't think any of these women are bitter.  They probably consider that they were blessed to have the avenues and opportunities to use their talents and gifts for the greater good.  Women are like that.  Yeah they are!

Ever heard of any of these women? I hadn't until I came across these interesting BIO snapshots.

- Émilie du Châtelet, Mathematician

- Julia Morgan, Architect

- Rosalind Franklin, Biophysicist

Interesting tidbit:
  • Emilie du Chatelet was named Gabrielle-Emilie; however, friends in her circle which included Voltaire {Francois-Marie Arouet (1694 - 1778), who later took the name of Voltaire} dropped Gabrielle and just called her Emilie. Her husband's name was the Marquis du Chastellet. But because Voltaire called her du Chatelet, everyone else did too!  [Click the embedded link her name above to read more.]

Celebrating the Genius of Einstein and #GR101

Started scanning a tweet stream this morning and found out that folks were celebrating the 101st anniversary of Einstein's Theory of General Relativity.  Collecting quotes is my hobby and in particular, always like to read what Albert Einstein (1879 - 1955) had to say.  Plucked this one from the Twitter feed.  It was shared by George Shiber.  (See embedded tweet below.)

Mr. Einstein died the year I was born.  It's not like we would have ever been best buds, but I fancy myself sometimes having a conversation with him.  Were we having a tête-à-tête, my response to his statement above would be:

"Not even a genius like you, Mr. Einstein, can comprehend all of God's thoughts. But if a fool would desire to understand just one of God's thoughts, they'd come out ahead.  (Wink. Wink.)"

Einstein always acknowledged The One Who gave him his brilliant mind.  That's what I most admired about him.

Who is the most intelligent person in the world's history? - Quora.com

From time to time I check Quora.com for their interesting Q&As. Like this question:

Who is the most intelligent person in the world's history?



Varied responses to this question that basically range from responders indicating: (a) naming names of historical people; (b) debating the validity and validation of the "IQ score" and (c) pretty much saying it's a dumb question!

Science and Education: Genome Brings Ancient Girl to Life

Old news (2012).  But still interesting.  In a stunning technical feat, an international team of scientists has sequenced the genome of an archaic Siberian girl 31 times over, using a new method that amplifies single strands of DNA. The sequencing is so complete that researchers have as sharp a picture of this ancient genome as they would of a living person's, revealing, for example, that the girl had brown eyes, hair, and skin. . . .

#EarthDay: Geoscientists have identified a chunk of Africa stuck onto the southeastern United States.





A long mysterious zone of unusual magnetism that stretches from Alabama through Georgia and offshore to the North Carolina coast appears to be the suture between ancient rocks that formed when parts of Africa and North America were pressed together 250 million years ago. ...
