Puzzle "3n+1" Maybe Solved

Puzzle "3n+1" maybe solved
Mathematical puzzle that has not found the answer for 74 years may soon be solved. Is a mathematician from the University of Hamburg, Gerhard Opfer, who claims to have found a solution.
Mathematical puzzle called the Collatz Conjecture or "3n +1" was proposed by Lothar Collatz in 1937. Puzzles that involve integer operations are denoted "n". In short, there are two conditions that apply in the Collatz Conjecture. If the integers (n) is an even number, then divided by two (n / 2) and if odd then multiplied by 3 then add 1 (3n +1).
Well, the Collatz Conjecture is expressed, if the operation continues to be done repeatedly, regardless of the numbers chosen to start it will always get the number 1 as a result. Verification has been done to the values ​​of 5.76 x 10 (18). However, without proper mathematical proof, there is always the possibility that huge numbers will deviate from this "law". This mathematical proof that has been owned by Opfer. He wrote in a paper which has now entered into the journal Mathematics of Computation for review because it could have no proper proof.
Now, does this math puzzle will be completely resolved? We'll wait. While waiting, maybe you could try to operate the numbers based Collatz Conjecture.
Try to take the number 6. Since 6 is even, then divided by 2, the result 3. Well, 3 is odd, then multiplied by 3 and plus 1, the result is 10. Then, 10 divided by 2 because an even number, the result 5. Then, 5 multiplied by 3 and plus 1, the result is 16. Number 16 divided by 2, the result 8. Then 8 divided by 2 results 4 and 4 divided by 2 again results 2. Figures 2 is an even number, then divided by 2 again and the result is 1. Well, if sorted, then deretannya is 6, 3, 10, 5, 16, 8, 4, 2, 1. For number 6, meaning attested. You can try to take another number. Want more challenging, take a big number.

Making Solar Cells on to Paper

Researchers at the Massachusetts Institute of Technology have created the technology in making solar panels that can be printed on a sheet of paper. This development makes the manufacture of solar panels cheaper and easier.

The solar panel of this paper is quite strong although it has been folded into a toy airplane. In addition, flexible solar panels that can be recharged when exposed to sunlight.

Printing process using steam instead of liquid. The use of a temperature less than 120 degrees Celsius allows the use of paper, plastic, or cloth as a container ordinary solar panels.

Researchers said, "The panel of this paper to be a breakthrough that could reduce production costs in the manufacturing of solar panels. It costs nearly one-thousandth the cost of panels made of glass."

Researchers said, solar cells printed on paper is still in the testing phase, the efficiency is still about 1 percent.

Professor of Electrical Engineering Vladimir Bulovic who participated in the study said, although the efficiency is still very small, this panel has been able to move small appliances. "I am sure in the near future we will refine these flexible solar panels," he said.

iPhone Battery Optimization

iPhone Battery Optimization
Tips for iPhone 4 this time is particular Questioning about the battery. Although compared to the previous generation iPhone batteries belonging to these four great does not mean we don't need to optimized it. This time I want to share the tips, I hope these useful. so these tips can be used in the iPhone 3G, iPhone 3G even in the iPhone 2G you can use. Because of the way the iPhone battery maintenance is useful in general.

Before continuing, in the App Store there are several applicationssupporting this battery maintenance, all good everything is good wejust have to sort out which one is right for us. In essence, the optimization is divided into 2 parts, daily and monthly. So here is more details.

Avoid Heat
iPhone does not like heat, so avoid putting the iPhone in locationsprone to heat such as (put in the car on a hot parking spaces, avoid contact with direct sunlight)

Battery Tips Daily
Keep in charge / content at any time before the battery is touching20% (recommended). Daily charging batteries is no limit in what level. If you want to make stuffing just do it

Monthly Battery Tips
Every once a month to do the battery calibration iPhone the easy way. Use the iPhone until the battery is home to 20% or less and recharge to full (this function is to make batteries more healthy andmake the calculations more accurate)

Turn off Push Mail
Activate if necessary, because the push mail is always access todata so that the battery will be drained faster

Turn off Bluetooth and Wi-Fi
When you really do not need two of these signals, better off alone

Turn off Vibrate
If you turn off the sound of the vibration alert mode, because it usesvibration motor so it will require additional power when it is executed. Better off alone

Auto Setting Display Brightness
With this setting the iPhone will adjust to the surrounding

Turn off EQ
Quote equalizer on the iPhone and it turns out cool but this is verywasteful of power. If you want to keep playing EQ, EQ settings in a few songs through iTunes

That was some optimization tips may be useful iPhone Battery :) :)

Fixing a Corrupt Mainboard

Motherboard Damage

Main board (motherboard) is the circuit board where a variety of interconnected electronic components such as microprocessors and memory (RAM, ROM, BIOS) and other controller chips and commonly abbreviated to mobo said. Symptoms and how to cope with a damaged motherboard :


1. Total dead
Check the power supply. In the state of the power cord from the power supply off, disconnect the cable socket mounted on Mainboard Atx1. Once detached, attach it back to the power cable, plug / cable shortkan green with a black cord, check that the power supply fan spinning? If the spin is a good power supply. Unplug the cable connections were Atx1 and reattach cables to the motherboard.


Check the Clear CMOS Jumper, whether in Clear or Free position,usually when a new motherboard, the position of the CMOS jumper on the Clear position.

Check the IC Chipset plugged in and on the Switch On, whether or not the excessive heat, over-heat means the chipset is already damaged. CMOS ICs for parts so far not sold free. check also whether the switch on its functioning. Unloading the Motherboard carefully, you try to clean the wear thinner, if you can not use thinners bottle in tin. After you dry clean. Replace the IC regulator which is located around the ATX power socket on the motherboard. Replace the capacity Elco 1000 s / d 3300 uF / 10Volt located around the ATX power socket on the motherboard. Be careful to make sure the component loading plug the power cablenot connected to the mains.


2. Computer Ok, But Not Appearing In Monitor

You try to watch and listen for whether there is sound or beep sound. If any, damage there is usually at the processor, memory and VGA.

Check the Processor, you try to hold the coolant is excessive heator cold? If overheating is the processor fan is not working properly then you change, but if cool means the processor does not work alias is broken.

Check the memory, usually when the memory is damaged audible beep on the speakers 3 times. Are turned off, pull the memory clean the pins using a pencil eraser to clean, then reinstall. If it means there's still broken one of his damaged IC.

Check your VGA card, unplug the VGA card, in the dead / off, you try to press, there are less chances you get or try to wash the feet /her pin. If the VGA card using the fan, clean the fan. If it still does not appear you try to check lest the monitor that is not a flame, to ensure that damaged the monitor or CPU, you try to press keys on the keyboard Numlock, whether Numlock lights her flame or not. If the flame is damage to the CPU.

Is the standard that I fix computers, I always clean it from dust,whether it be the motherboard, memory, cdrom, floppy disks, etc.,because it is so what else could affect the computer in a dirty / oldis not cleaned. But you must be careful in the proceed and do not rush.
3. Hang And Often Off / Restart (Reset) Himself
Check the Power Supply, try using another power supply if it still restarts itself or hangs. If after replacement power supply turns normal / good, power supply means there is a problem. Change can be fixed if only because I am not sure whether it is still able to function properly, because the power supply is a vital component. Especially for the current price very cheap power supply, I suggest changing it.

Check whether there is virus, anti-virus program should always be installed and enable auto protect her. I used to use Kaspersky Internet Security Anti-virus. You should frequently update your antivirus because if there is a new variant virus, your anti-virus willdetect at once eliminate the virus.

At the moment there hangs and bluescreen messages such as"error vxd at address ...", there is usually a problem in memory.Clean the memory is like a step above. Try to reinstall Windows. If it still hangs / restart itself you try to check the motherboard, you notice physical changes in particular components of Elko /capacitors, which are writing a black round capacity between 1000uf/10Volt s / d 3300 uf/10 volts, usually seen, if the damage visiblebloating / swelling and remove fluid or rust.

CMOS Checksum Failure (Low Battery)

A message appears CMOS failure (damage to the CMOS battery, replace battery) Setting the date, time and other configurations in the BIOS to change (After replacing the battery, did reset the settings in the BIOS).
