How much more light does one collect with a 10-meter diameter telescope...?
How much more light does one collect with a 10-meter diameter telescope in 10 minutes than with a 1-meter diameter telescope in 100 minutes?
A. 1/10th as much
B. Same amount
C. 10 times as much
D. 100 times as much
collection rate is proportional to area or the square of diameter
so
rate for 10 m is 100 times that for 1 m
then
the 1 m is in use 10 times as long
so
the answer is 10 times as much for the larger scope

Light Therapy Glasses Luminette Finally in England
Although English people are only just starting to discover light therapy lamps, there is a new product on the market : the light therapy glasses called LUMINETTE.
This products' clarification was done by researchers of Liège University and its' industriel partners who wanted to creat an original model giving maximum theraputic effectiveness bringing the source of light to the eye without any complications.
The advantage of this high-tech product is that you can wear it while going about your business and still benefit from the light therapy at work or while doing your daily activities without any discomfort you can even wear the luminette with perscription glasses.
A reminder for those who do not know about light therapy yet. It is just as the name suggests therapy from lights. Light therapy started in the United States thanks to a famous professor Rosenthal who first discovered the link between winter depression also called seasonal depression and the lack of light.
The treatment consists of a daily exposure to a light therapy medical lamp due to a loss of sunlight in winter. It helps to beat seasonal depression, tiredness, gloomy humour and to find energy and vitality in the middle of winter.
The use of these lamps is also recommended to night workers to people who do alot of travelling, to compensate for the effects of jet lag. In these 2 cases, the straightforwardness and the easiness of the use of the luminette can be particularly appreciated.
