How can I get better at tennis and what are some tips?

I just started tennis this year and I’m actually pretty good but tomorrow at practice we are doing some sort of match thing to decide the 3 people the won’t be playing quads (they’ll still be on the team but the day we have quads we have 3 too many girls). I really want to play in this and my biggest problems would be aim and backhand (I can get backhand over and in but it usually goes really high even if I tell myself to tilt the racket downward). Any and all tips are appreciated

OK, to get through tomorrow, before you can PRACTICE more, which is the main thing you need.

1. PREPARATION – Get to your hitting position as quickly as you can. Move those feet. Take your baby steps to get your position just right.

2. PREPARATION – Get your body turned, feet lined up, shoulder turned, weight on your back foot, ready to move through the ball when you swing.

3. SWING – Keep your eye on the ball.

4. SWING – Do not move your head until you have completed your swing.

5. SWING – Complete your follow through.

There are of course many more “tips” but if you write those 5 down on a card and read them over during the day, then remember then during your practice matches, it should really help.

Then you need to practice a lot, and we can add some more tips.

Good luck.

Music Angel KT88 replaced with KT120 tubes

please please help wats wrong with me..?

ok…its been going on for a year n a half now..! i had a ctscan a year ago which came bk normal..ive had a sinus scan which came bk normal..wen it started it started with a funny feeeling behind my eye n like a pressure feeling in my head..then my eye dilted more than the other..then two weeks later i had a fit and passed out..dnt no if this is related..i started to feel slightly confused like i couldnt think fully…but was ok..now i feel totally confused cannot take in anything hardly n i have a funny feeeling up my nose n in my forehead..i can feel like really thin tubes n wen i blow my nose they are really sore theses tube things..wat the hell is this..? im not depressed or anything..please help me its totally ruined my life..is it possible sumthin cud have been missed on the brain ct scan..i had that over a year ago n things have got much worse since then.,.? wat cud it be its very odd no one nos what it is..?

Maybe get an eye test. Boots do a really thourough one where they can check for abnormalities with your retina and stuff.

Also get straight back to your GP and get some more tests done…especially if it is worse and you have had a seizure – something is obviously not right (and Yahoo is not the way to get a diagnosis!)

Good luck

What’s the difference between a tube and a solid state guitar amplifier?

I know tube sounds better.

I’m probably going to get a little technical here, but stay with me.

First, you can’t make a blanket statement that “tubes sound better”. I’ve heard some very good solid state amps in my day, and some really horrid tube amps. So, just because an amp has a tube in it doesn’t automatically make it a tone machine.

I’m going to assume that you question is asking “What’s the difference in the tone of a tube and solid state amp”, so that’s the avenue I’m going down.

For the most part, tube and solid state amps will behave much the same way while they are being operated in their linear region, which is a fancy way of saying that you haven’t turned it up loud enough to distort. Tube amps, in general, have a higher input impedance than solid state which tends to load your guitar pickups less (and thus will sound a little different).

The real difference comes when you start turning up the signal level to the amps, and how they handle the overload.

A solid state amp will keep amplifying a signal right up to the point to where the amplification device (transistor, op amp, FET, etc) runs out of headroom. And at that point, it abruptly stops. This results in a clipped waveform (think square wave) that contains predominately odd number harmonics. Our ears perceive this kind of distortion as abrasive, or non-musical. It’s the way a lot of fuzz and distortion pedals work.

A tube, on the other hand, does not behave like this. As you turn up the signal level to a tube, it’s starts to compress the signal. As you turn it up further, the tube does not clip the signal as abruptly…it’s more of a limited signal than clipped. Combined with the output transformer in the circuit the signal consists of predominately even numbered harmonics, which our ears perceive as musical.

Tubes (power tubes specifically) can have a very large dynamic range…much larger than solid state devices. This contributes to how a guitarist can back the volume on his/her guitar down a bit and clean up the sound.

OK…probably way more info than you wanted, but there you go.

Storing amplifier?

I have a Marshall AVT50 Combo amp. Due to construction on my house it is stored in an unheated garage. Will cold temperatures damage the preamp vacuum tube?

Vacuum tubes are pretty resistant to different storage conditions. Some people even cryogenically treat (freeze) them. The preamp tubes are very inexpensive anyway… Frequent temperature changes can cause condensation moisture and corrosion on electronics though. It would be far better to store the amp in a temperature controlled environment.

Quantum Dots and Fullerenes Team Up For Better Nanoscale Solar Panels
Research scientists at the Brookhaven National Laboratory have developed a process to pair quantum dots with fullerenes in photovoltaic cells in order to improve the effectiveness of solar panels on the nanoscale. In a step toward engineering ever-smaller electronic devices, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have assembled nanoscale pairings of …
