Christmas Tree & Wine Glass Challenge

 

 

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 Akasaki, Hiroshi 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 efficient 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.

 Christmas Tree Puzzle Solution Part 1

 

The art or science of steganography involves hiding a message in a picture, file or text in such a way that it is not immediately obvious to an observer that a message is concealed at all. The practice has a long history, from Ancient Greece through to present-day digital techniques. This is an example and to solve the puzzle you need to find an eight-letter answer. We wish you a peaceful Christmas and a Happy New Year.

 

Missing Letters in Order: noelareatsdeveopthee

 

You are now required to find the eight missing letters to complete the sentence.

 

nobel laureates developed these

 

Eight Letter Answer: blueleds

 

Missing Word: blue leds

 

 

You now have:

Nobel laureates developed these, blue LED's.

Wine Glass Puzzle Solution Part 2

 

For those readers who enjoyed that puzzle here is an additional challenge. To solve this puzzle you just have to find a tetragram which seems to be missing altogether. The tetragram sounds like a drink they would probably all enjoy.

If you look up the 2014 Nobel laureates in Physics, who developed blue LED's, you will find the following....

Hiroshi Amano

Nagoya University, Nagoya, Japan.

 

Shuji Nakamura

University of California, Santa Barbara, USA.

 

Isamu Akasaki

Nagoya & Meijo University, Nagoya, Japan.

 

Adding eight additional letters to the original letters below spells out two of their names:

 

The eight additional letters are: is am u aka

 

hiroshi amano     shuji nakamura

 

 

Missing from these are another four letters, which when added will give the name of the remaining Nobel laureate: Isamu Akasaki

 

The four additional letters are: sa ki

 

isamu akasaki  (saki)

 

The solution is therefore “saki”. This is a tetragram (which means a word consisting of four characters) that sounds like a drink (sake) that the three Nobel laureates, all being of Japanese descent would probably enjoy.
