Eating Stars: L’air du temps **
There is always a first time. It’s like the first kiss, you’ll never forget. But this experience is better - it is spectacular! I’m talking about the first time I had the honor to eat in a Michelin starred restaurant: L’air du temps in Belgium.
The Doppler effect is observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding. It is important to note that the effect does not result because of an actual change in the frequency of the source. Using the example above, the bug is still producing disturbances at a rate of 2 disturbances per second; it just appears to the observer whom the bug is approaching that the disturbances are being produced at a frequency greater than 2 disturbances/second. The effect is only observed because the distance between observer B and the bug is decreasing and the distance between observer A and the bug is increasing.
The Dopplereffect can be observed for any type of wave - water wave, sound wave, light wave, etc. We are most familiar with the Dopplereffect because of our experiences with sound waves. Perhaps you recall an instance in which a police car or emergency vehicle was traveling towards you on the highway. As the car approached with its siren blasting, the pitch of the siren sound (a measure of the siren’s frequency) was high; and then suddenly after the car passed by, the pitch of the siren sound was low. That was the Dopplereffect - an apparent shift in frequency for a sound wave produced by a moving source.

LG showing off 5 inch flexible screen for smartphones.
LG will be showing off their latest flexible and unbreakable 5 inch OLED display at this weeks SID display week in Vancouver.
The plastic display will be shown off alongside other 5 inch and 7 inch HD Oxide TFT panels which have a bezel that’s only 1mm wide, allowing for smartphones and small tablets with virtually no frame or border.
