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....

Sixty Symbols - Blue LED's for the University of Nottingham
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2014.
The Nobel Prize in Physics 2014
Shuji Nakamura
University of California, Santa Barbara, USA.
Hiroshi Amano
Nagoya University, Nagoya, Japan.
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.
