The explanation is shown in the last picture of the page found by thomas.\n\nI think also a degree in maths or physics or so can work to fill the generation gap.\n\n(Actually I think you owe love and devotion to your mom even before the day when elecricity will miss and your clock won't work anymore...)\n\nEach of "hours", "minutes" and "seconds" have two sets of dots to be read in vertical.\nThe first set on the left has only two dots because hours can only reach the number "24", so you don't need the "4" and "8" leds.\n\nThe thing to know (try and believe) is that every number from 1 to 9 (in fact from 1 to 15) can be written as a sum of 1, 2, 4, and 8:\n1= on off off off  (read in vertical from bottom to top)\n2= off on off off\n3= 1+2  so 3 = on on off off \n4= off off on off\n5=1+4= on off on off\n6=2+4= off on on off\n7=1+2+4= on on on off\n8= off off off on\n9= 1+8= on off off on\n\n---To all mums online---\n\np.s.I don't like websites where they teach kids not to respect their parents

An essay? You have to write an essay for school and you want someone to write an essay for you? What on earth? \n\nWhy don't you look on the web and do your own research? What is wrong with you? \n\n\nI will give you a little bit to get you started. \n\n1. There is a HUGE amount of documentation for water clocks during the time of the Greeks and Romans. \n\n2. For millenia, the movement of the stars and other celestial bodies was used for time keeping. Look at stonehenge and the Mayan calendars for examples of ancient uses of astronomy for time keeping. \n \n\n3. Springs and gears are another mechanism that came later (I think the spring is called an escapement mechanism).\n\n4. You should check out the device called the antikythera  mechanism, which might have been some sort of clock.\n\n4. There were atomic clocks developed after atomic physics was discovered. \n\n6. Quart crystals made accurate and cheap wrist watches available. \n\n\n7. The pendulum of course was well-known. I think it was Galileo that timed it with his own pulse and realized that a pendulum was regular.\n \nThere is a lot more to this subject. Look on the internet. Go to wikipedia.

..He was a brilliant scientist. He had a photographic memory and he won a court battle for the credit of the patent for the radio. Long after his death for the claim on the invention of the radio over Marconi. He died around the time of WW2(not becuase of the war).\nHe invented solutions and saw the invention in his head and never took many notes...The things you mentioned are yet to be confirmed and could very well be true, some of his inventions are mind-boggling.\n\n...you should have a look at the book : \nNikola Tesla - The Man Who Invented The Twentieth Century. \n\n- hope this helps...thanks.

Hi there:\n\nThe cell phone keyboard with the typical ABC\nis, as one answerer stated, a clone of the Alexander Graham Bell    configuration put out by Bell Laboratories, many years ago.\nAs someone stated, this crude way of using the numbers to\nget " words" was a memonic aid, so that "ASH 277" would be easier to remember, than all numbers. Since there were only a few phones, by grouping 3 or 4 numbers into a word, meant you only had to remember the last few digits, so " ROCK " would be the first area code for 999 phone numbers, and you just had to remember the last three digits.\n ( more Bell Labs trivia - did you know that the # sign is an octothorpe? This is out of a 1967 RED BOOK handbook for Bell Linemen... since then the name has been lost, and no one knows what it is called anymore, not even computer reference guides....   -- and, Alexander Bell wanted a word to sign in on a phone call CLEARLY, and searched around the world for a sound that was easy to recognize - the best he could find was the call for fishermen in foggy weather, who yelled AH - Looo, which reverberated like a fog horn and helped to prevent two sailing ships from hitting each other - He modified it a bit and invented the word " hello ", which never existed in the English language until he had all his operators use it... )\n  \n As for the QWERTY layout of the keyboard, here is a previous answer that I gave... your question is asked repeatedly on the ANSWER forum...\n\n__________________________________\n\nEarly typewriters were mechanically crude and the swing arms that\nhad the letters on the end moved 6 inches or more from a circle around\nthe center of the page. If two arms reached the same strike slot,\nthey jammed together, often bending the thin swing arms.\n\nA group of Engineers was given a typewriter by Remmington in New York, to design a jam- proof machine. Instead, the Engineers looked at a data base of the most used and least used\nletters of the English alphabet.\nThey put the most used letters on the LEFT hand, since most people are right  handed, and the most used letters on the weakest, least used fingers - note that  the letter "A" is on the baby finger on the left hand. The baby finger on the left hand was designated the weakest, most difficult to use finger, while the letter A is always abound across almost all amounts of actual typing.\nThe ploy worked, and typists who were using the common keyboard of the day, with all the letters in alphabetical order, slowed to an absoute crawl.\nRepairs of jammed keys stopped immediately.\nDVORAK was designed to improve typing, and " reportedly " quadruples the words per minute.\nRAND in England designed a keyboard with two bowls shaped to\nfit the human hand natural swing movements, so that the typist\ndoes not "reach" for top row keys and left and right keys, but\nmoves only the fingers, and unlike the old typewriters, which had\nkeys that would have to be pressed down against huge springs,\nabout one to two INCHES, the RAND keyboard had touch-screen like keys, that have no visible movement at all. The words per minute reach 2000, easily, by anyone with a bit of practice.\nToday, on a typical computer, programmers and general public are considered " good " if they can do 30 or 60 words per minute.\nSecretaries start at 120 words per minute.\nMost of the computer people I know still use two fingers, including\nsome of the fastest and best programmers, following the GIGO rule.\n(( Computers use a stack of memory, which programmers fill and recall with numbers, using either FIFO or FILO, First In, First OUT, or First in, Last Out. All early calculators like the HP65 I use, with RPN ( Reverse Polish Notiation) use FILO ). GIGO is a parody of this terminology, with Garbage In = Garbage Out. ie. Typing in huge amounts of poorly written and poorly tested program code, is not as fast as typing in well written, well tested

If you don't count the abacus, which is ancient, then Blaise Pascal invented the first mechanical computation machine in France in 1642. Check it yo!\n\nhttp://www.thocp.net/hardware/pascaline.htm
