Fahrenheit 451 Ray Bradbury How plausible is the future envisioned in this novel? The large screen televisions are believable - in fact‚ technology is currently leaning towards 48‚ 56" TVs that nearly fill up the whole wall. When this book was written‚ it seemed like an obscure possibility that TVs would ever be that big. The Seashell earphones are like CD players. People can be listening to them in one ear and having a somewhat normal interaction with the half of their brain that’s not listening

possible for a contactless tachometer to take the readings from a certain distance. This is the main motivation behind choosing this project. This contactless tachometer uses the IR transmitting and receiving technique. This is achieved by receiving IR rays from a reflecting spot on the shaft of the motor. The speed of the motor is controlled by PWM from the microcontroller. The project uses a microcontroller and a pair of sensors (Transmitter and receiver) which gives the output to the microcontroller

The name Blu-ray is a combination of “Blue” for the color of laser that is used‚ and “ray” for “Optical ray”. The thrust for an advanced format of data storage on optical disc led to revolutionary introduction of BLU-RAY DISC. This advances in the race against its competitors DVD (Digital Video Disc) & AOD (Advanced Optical Disc) in that it has high storage capacity‚ advanced security and privacy features and the A/V high quality O/P (generally video) of the media files stored on it make’s

LI-FI (Light Fidelity)-The future technology in wireless communication Pooja Abhnag1‚ Pratima Tarte2 Department of Electronics & Communication Dr. D. Y. Patil Polytechnic Address 1poojaabhnag13@gmail.com 2tartepratima@gmail.com Abstract— Li-Fi is a new wireless communication technology which enables a wireless data transmission through LED light. Li-Fi is based on a unique ability of solid state lighting systems to create a binary code of 1s and 0s with a LED flickering that is invisible

Tachyon particles are theoretical particles that supposedly have a minimum speed of the speed of light. Tachyons‚ (from the greek word ‘tachys’‚ meaning swift)‚ have never been found in experiments‚ but scientists think that they exist as faster-than-light “quasiparticles”. In the 1960s‚ some physicists wondered what would happen if matter could travel faster than the speed of light‚ something that is supposed to be impossible according to Einstein’s Theory of Special Relativity. Tachyons were first

X-ray Powder Diffraction Analysis: Principles‚ Instrumentation and Applications M.S.Pandian Department of Earth Sciences‚ Pondicherry University‚ Puducherry-605014 Introduction X-ray powder diffraction analysis (XRD) is perhaps the most widely used X-ray based analytical techniques for characterizing materials. As the name suggests‚ the sample is usually in a powdery form‚ consisting of fine grains of crystalline material to be studied. The term ’powder’ really means that the crytalline domains

Danielle Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs

often as they want. In case you don’t yet a sauna‚ you should consider getting one. You don’t know if you should choose a far infrared or a near infrared sauna? If so‚ then here is the difference between far infrared and near infrared saunas. Energy consumption When it comes to energy consumption‚ a near infrared sauna will definitely use less energy than a far infrared one‚ due to the fact that it operates at a lower temperature. This aspect is extremely important‚ so you better have it in mind

How To Make An IR Mini Emitter Tools Parts Stanley knife‚ or very sharp blade Screw cover Small drill bit Infra red LED (Maplin code CH10) Hot glue gun Screened cable Soldering iron and solder 3.5mm mono jack plug (Maplin code HF81) Step 1 Start by using a very sharp knife to remove the small plastic hinge joining the two sections of the screw cover together. Step 2 Using a small‚ sharp drill bit (I used 3mm as this matched the diameter of the cable I was using)‚ make a hole in
