December 10 – Human Rights Day - and Nobel Prize Day!

Posted on December 10, 2020

This is an update of my 12/10/2009 post:
 
Human Rights Day:


“All human beings are born free and equal in dignity and rights.”

These are the first words of Article 1 of the United Nations' Universal Declaration of Human Rights. This is a day to embrace diversity and work to end discrimination.

In the U.S., the LGBT community is only slowly gaining the legal rights as the larger society - with some achievements and some setbacks. Also, women are still not unambiguously declared equal in the constitution. Of course, even with the protection of the law, there is still racial discrimination to root out and eradicate. Around the world, examples of sexism, racism, and other forms of bigotry still exist and can be found and eliminated.

Also on this date is
Nobel Prize Day:



This is the anniversary of Alfred Nobel's death, and today Nobel prizes are awarded in literature, economics, and the sciences, as well as the coveted Peace Prize.

Watch the webcasts of the Nobel award ceremonies here.

Create your own serious or seriously funny awards!

Award the people in your life. From “The Banana Award” to the friend with most a-peel (appeal) to “Keeps Us in Stitches Award,” with the prize of a needle and thread, here are some ideas.

If you could name an award after yourself and pass out millions of dollars to worthy people, what sort of achievements would you award? What would your award look like?

October 7 - LED Light Day

Posted October 7, 2019


They weren't the first to invent LED lights. Red ones had been created in the late 1950s and early 1960s, and green LEDs were created after that...

And then, finally - in the late 1980s - Isamu Akasaki, Hiroshi Amano and Shuji Nakamura invented blue colored LEDs. This discovery finally allowed people to create white LEDs, because a bright blue LED beneath a yellow translucent covering makes a beautiful, warm white light.

If all LEDs were still red, we'd use them a lot less, wouldn't we???












On this date in 2014, the three Japanese physicists won a Nobel Prize for their technological development.

So...what's the big deal? 

LEDs are extremely efficient, long-lasting, and can be used without access to a power grid. They don't get hot, they save energy, and ultimately they save a lot of money.


Many of us in the developed world are switching out all our incandescent bulbs - and certainly our horrible (and mercury poisoning!) fluorescent bulbs - yuck! - to LED light bulbs. As a matter of fact, many of us already did so a long time ago and have been saving power and money for a while now!


And LED lights are used in almost every electronic device - we don't really know or notice all the LEDs surrounding us.


Now, if we can just switch over from wood-burning and other greenhouse-gas-emitting technologies to LED lighting in the developing world - well, that would be awesome for everyone!

Check out this and this video about LEDs. And here is an article, complete with diagrams and a video, about how Light Emitting Diodes work.
