Nobel Prize in Physics 2014 Awarded for Work on LED Lights

This year’s Nobel Laureates are rewarded for having invented a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources.

When Isamu AkasakiHiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a fundamental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.

They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.

White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.

The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.

The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.

My therapist asked me to create something “motivating” so I made these.

lol.

I really love these, and I reblog them every single time. Some of you don’t realize how easy it’s to forget to do some of those stuff or how hard they can be some days.

now i feel like ive actually accomplished something today thank u ily

I have finally hit my breaking point. For as long as I can remember I have endured my mother’s abuse, whether it is verbal, emotional, or as seen here physical. I can expect some act of violence on a daily basis, and her beating me is not an usual occurrence, but today something snapped. My mother did this unprovoked, and this time she didn’t stop. Usually it’s bad for a little while and then she’s done, today it went on for what seemed like forever. At a certain point I decided I was going to do something I never do, call the police. You see, my mother is a highly respected and very well known person where I live. She is on the board of ed, worked for CPS for many years, and is close personal friends with people like the local chief of police, director of our local CPS unit, and so on. I always knew that calling wouldn’t go anywhere and just upset her more, but today I had to try. While she was kicking me I found my opportunity, and somehow managed to get away from someone more than twice my size. I ran as fast as I could, knocking things over behind my, trying to find a phone. I dialed and they listened and my mother proceeding to beat me over it, while I screamed for help. For the second time today, I managed to get away from her and ran to my room. I barely had enough time to lock my door, before she starting trying to get it, to the point that she ripped my door off the frame. I decided I was going to stay locked in there, until the police came. The past few months I have been collecting evidence against her, voice recordings, pictures like these, and videos of her violence, so they couldn’t dispute what was going on. But I was dead wrong. 

When the officer finally came up to my room, I attempted to tell him my side of the story, but before I could get a sentence out he silenced me. HE told me that this was my mothers house, and I needed to live by her rules. If I didn’t she had the right to punish me. He also told me to be tankful for her, because he wanted to press assault charges against me. finally, he refused, despite my begging, for him to take me to a shelter for teens. 

I am utterly disgusted by the injustice that occurred today. I pray there is no one else out there who is living in such a situation. I am not sure exactly what I am getting out of writing this, except maybe that it’s just nice to be able to open up about this, when I have had to keep it a secret my whole life. idk. sorry for posting such heavy shit. 

Signal boost the fuck out of this
