Mathematics is one subject that if you know it well, you will enjoy it but if you don’t then it will make your life hell. Learning maths can be fun if it does not involve strict maths teachers (I have usually found maths teachers to be quite strict) and student is able to get answer and clear explanation of everything no matter how simple it is or difficult. Students are shy in asking questions in class because they think they question they are going to ask is very simple one and students of class will make fun.

Math answers if easily available with clear explanation then all left for the student is to give it a time in understanding how its done, which formulas are used, learn the formula if he/she don’t know it already and then practice the question few times. Practicing is very important in mathematics. I understood this when I needed Calculus help and no matter how many formulas I learned, I was not able to do tougher problems of calculus. Then I came to know that practicing is all I need and I will have to practice so many problems that in exam no calculus problems should look new to me. Only then I would be able to solve else it may take lots of time to solve it and in exam we have limited time. Precalculus help is also an important thing to get equally for better understanding of this topic.

If you drive a car then sometimes you must have noticed fatigue and you might have not given it attention thinking of just temporarily weakness. Problem can be with your car too! After some usage the driving may not remain the same as it is with a brand new car but you can do some bits to keep it running like “out of showroom” and most importantly save yourself from unnecessary fatigue.

When we drive the car, we have so many things to do drive car safely on road that not for a single minute we are relaxed. This lead to brain not giving you feedback of how hard your clutch pedal has become and how much pressure you are putting on brakes and accelerator. Even gear change may not be as smooth as before but since it’s a small change that we don’t notice it but it doesn’t mean its not affecting our body.

Next time when you start driving your car, take your car on a quite and lonely road where you can concentrate on the feedback your car is giving and not risk others on road while noticing all this. Drive the car with calm mind and see if you need to put more pressure on clutch pedal than you needed before or just anything that is causing discomfort. Stop and make a list of it. Next time you go to service, get those all fixed with your full satisfaction. Before you go for any major repair, it will be better to check a new model of your car. Suppose you feel that clutch is tight and your service center suggest clutch overhaul then first check a new car in showroom which will give you feel of exactly “how much” tight is your car’s clutch. If there is only slight difference then tell them to change clutch cable only and see if that brings the clutch smoothness and lightness back to normal.

Other cause of fatigue is longer drive on congested roads. Traffic means you will have to change gear frequently, use clutch also again and again, basically you will be involved in doing many task for longer time that will strain your body and mind. Avoid routes that are prone to traffic jams. Also carry some slow and soothing songs with nice tune that you should listen on low volume, it will keep you relaxed and you won’t get irritated easily.

Use AC if it’s hot outside and even if you feel you can do without it, switch it ON. We don’t feel much heat because when door glass are rolled down, we get lots of air circulation but under the seat there is no air circulation and without our knowledge its getting too much heated there.

Footwear also play important role. If you wear shoes with thicker soles, it gives less control on all the pedals operated by foot. Wear shoes with thinner soles but not too thin either. Just see which of your shoes gives best control and ease of operation as it can vary from person to person. I like wearing thin sole sandals as they give me best control and comfort while most people like proper shoes.

Now you can save you thousands of bucks that you might spend on buying car or bike or just any lead acid battery even when its not needed. Lead Acid battery plates develop sulphur with aging and this blocks current leading to low voltage and a time comes when battery is no more able to maintain 12v and car does not start.

I have tried this trick on my car battery which went dead few days back, just 10v was left in it and was going down to 4v on using self. First I tried charging it using battery charger for one whole day and night but I found as soon as I remove it from charging, it would go to 10v at once. So battery was dead, there was no reaction (bubbles) in one of the cell. I was about to change my battery then found this tip and it worked for me

The real thing:
===========
When you are not able to recharge the battery and it won’t maintain 13v then do this.

1. Open all the caps (from where you fill water) of cell and drain the acid. (You can use this acid to remove algae). Please do this cautiously, wear surgical gloves and goggles to protect your eyes and hand from acid.

2. Take an empty 600ml plastic cold drink bottle, fill it with distill water and add 2 teaspoon of magnesium sulfate in it. Shake shake shake! shake it well untill all the salt gets dissolved in distill water. You can get magnesium sulfate from people who supply chemicals in school labs.

3. Fill each cell with this magnesium sulfate solution you just prepared, don’t overfill, just about 0.5 inch above plates is good. Tap the battery from each side so that air bubbles trapped in plates escape.

4. Don’t put the caps back, leave battery open and put it on charging. I used 5 Amp charger for my 35 Amp car battery. Charge it for atleast 24 hours. Use atleast 10% current for charging, for example your battery is of 12v and 65 Amp then use atleast 6.5 Amp current and 13.8V for charging. I would recommend slightly higher of about 8 or 9 Amp.

5. Remove battery from charging and check voltage. Wear your goggles and peep in cell using a torch to see tiny bubbles coming up from each cell plates. This indicate that your cells are working! If you don’t see this then your battery needs more charging. If you do see bubbles and battery voltage remains constant between 12.6 – 14v then you just saved your battery and it can be used in your car now!

The magnesium sulphate solution will turn into acid when battery is charged so you don’t need to add acid later. If you feel electrolyte level has gone down after this long charging, you can add distill water. But remember don’t overfill the cells as overfilled cells with experience slow charging.
