dear adam This is from the Milton school academy comp. coordinator. OK Adam, I can send you my answers but I can't engage in extended correspondence ... 8080 is an 8-bit computer, I think it showed up about 1977. ...CPU means Central Processing Unit. ...Edward Siegfried Milton Academy sent via Milton Academy Computer Center
Do you know when the Intel 8080 was first released?
Do you know what CPU stands for?
Do you know how many bits the Intel 8080 was?
1974 ... Central Processing Unit ... The 8080 was released on 4/1/1974. It's clock speed was 2 MHz, bus width was 8 bits, it had 6,000 transistors on it and could address 64 KBytes of memory. It was also 10x the performance of the 8008 which had been released exactly two years before.... Alex Slawsby
dear chris i have often found that without the laser printer, i would most likely not go anywhere in life. yetwit this gret invention, my social habits have blossomed into adulthood. i give it two thumbs up. deveraux brown
Thanks a lot for giving me all that great new information on my technology item! :)
Now I have a few questions for all of you:
1) Do you think computers are good for society or bad? How come?
Computers aren't good or bad. They are simply hunks of wires and sand (silicon). People (and how they use technology) are good and bad. People have done "bad" with books, their voices, etc....
2) Can you think of some problems caused in society by the invention of the ENIAC? Can you think of why this might be considered a "good invention" or a "bad invention"?
ENIAC made calculating trajectories easier (not easy) and war is a bad thing. Or is it? It controls population growth (albeit violently) and forces governments to invest in progress. Good or bad? Who knows? If we all got along, would we still be living in caves? Would that be good or bad? That's another paper... ENIAC started us on the road to technology that has also helped save millions of lives with medical advances (good or bad?), allowed for computer simulations of such things as automobile crashes and nuclear tests (good or bad?), get my drift?
3) Would you consider the invention of the ENIAC to be an important one or a minor one in the history of civilization? Why? Important. During wars, when the government sinks that much money into research, advances come much more rapidly. Too bad they don't understand that this works in peace-time too!
4) Can you think of someone you know who either likes computers too much or hates them too much? Describe that person a bit. There are many people who like technology so much that they ignore their friends and family. This is bad. The flip side is the technophobe who is so scared that they cannot function in today's technologically-based society. These are the people I try to help. It's part of my job.
5) Since I have not gotten many replies to my request of anything you know about the ENIAC (besides you, Lemoyne!! Thanks a bunch for spend that much time!! :) ), I will ask you again: What do you already know about the ENIAC?
BE MORE SPECIFIC WITH YOUR QUESTIONS AND YOU WILL RECEIVE MORE ANSWERS. NARROW YOUR SEARCH. DECIDE WHAT ABOUT ENIAC IS REALLY YOUR TOPIC. TELL US WHERE YOU HAVE ALREADY LOOKED AND WHAT YOU ALREADY KNOW THAT YOU WILL USE IN YOUR PAPER. Good Luck!
Answers below. Lemoyne S. Dunn lsdunn@tenet.edu Technology Coordinator Johnson Elementary Southlake, TX
That's not a very specific question. I presume you've already at least checked encyclopedias and come up with the following info: >Electronic Numeric Integrator and Calculator (ENIAC) 100 ft long, 10 feet high, 17,4800 vacuum tubes (generated heat like mad) Built to calculate military trajectories by Dr. John Mauchly and grad student J. Presper Eckert at University of Pennsylvania. Not completed until 2 months after the end of the war. 5 multiplications/second (much faster than Mark I)
Now the stuff you may not know: (from the Nov. 15, 1996 Wall Street Journal - highlights at http://wsj.com) It was programmed by re-wiring the front of it. Not only did you have to tell it what to do, but you had to time the instructions within 1/5000 of a second. This was done by 6 WOMEN, all mathematical geniuses, because the work was deemed "too tedious" for men. These women, called "computers", were Marlyn Wescoff Meltzer, Ruth Lichterman Teitelbaum, Kay McNulty Antonelli (eventually married Mauchly-her real claim to fame), Frances Bilas Spence, Betty Snyder Holberton (granddaughter of an astronomer) and Jean Jennings Bartik (a 20-year old math prodigy).
Test run: Feb 1946. Calculate trajectory for 155 millimeter shell. Handled by Bartik and Holberton. Afterwards, men went out for celebration dinner. Women went home - their names almost forgotten.
Sex bias lives on... When the commander wrote up a history of the project, he only listed the women's names, misspelling one, and identifies which engineers they married.
Kathryn Kleiman (1984) made a video about the five surviving Eniac programmers, but software companies refused to acknowledge that women could have contributed that much. Until Ms Kleiman made a stink, they were not even invited to the 50th anniversary gala dinner. Where would technology be today without these women? Good luck on your project. Lemoyne S.

They were mass produced in the 30's, that is when the first automatic washing machine was made. J. Inman (par)
A plus of the dishwasher is that you don't have to wash the dishes by hand. but on the minus side you have to pack it and unpack it. Why did you ask that question. What product did you do for the technology project? Mr. Inman
I think that the washing machine has had a huge impact on society 'cause now people change their clothes everyday instead of every week so theirs not as much bacteria every where. Chloe Lewis,Park School
dear diana It always cleans your clothes it sometimes shrinks your close (bad) it can shread your clothes (bad) it gets stains out Jojo emout02.mail.aol.com
The pluses of the washing machine are that it cleans clothes automatically - without having to do it by hand. you just add some detergent, and push a button. However, in the fifties when the washing machine was first used, it was supposed to lighten the work load of the house wife. But oddly enough, it did just the opposite, making it easier to do laundry, so that the woman would do load after load after load. So those I would say are the pluses and minuses. Nina
This is probably a trick question as there are a few different attributions so I will be safe and say that in 1609 Gallileo (Italy) invented the first astonomical telescope --there were others who were earlier on the basic - your pen pal C Bennet (par)
This is a heavy question about which I have never given much thought but I would say that the invention was good for the world because it increased mans understanding of the world and his place in it and its relationship in the solar system and though the truth may have shaken some religious assumptions it is none the less the truth...is that enough for today? C. Bennett (par)
It had an excellent effect on the world. First it taught us to be less egotistical (no the universe does not revolve aroung the earth), and it gave people fresh ideas. I mean, just look at NASA and all the exciting space exploration going on these days. If someone hadn't turned a lense to the sky to see what was out there, this age of discovery never would have come about. Ryan Boinay
I don't think that remote controls are bad for society at all except for one reason. They started the beginning of the creation of a new line of electronics that do every think for you such as personal organizers, home banking on email, email, etc...... I don't know anyone who hates or loves them too much and no problems have been created except when you lose the remote control instead of changing the channel, you spent an hour looking for it. Lizzie Graef,Park School
I think remote controls are a very good thing for society. I suppose a bit of laziness is created but I don't mind. I don't know anyone who is either very much for or against remote controls. Jessie Sandell '97
Hello Josh Raymond: I got your questions regarding the TV remote control, but they are hardly simple!
1) I think without a doubt computers are good for society. In the first place, it's gotten people to write to each other again, like we are doing now via e-mail. Not only is this (usually) a sign of communication between two people, but writing forces people to actually read and write, skills that come in very handy indeed. And computers also make it possible for our letters to get to each other without having to bother postal employees, which is good because they are already much too tired carrying junk mail. Computers are like tireless gnomes who go around doing all the really boring things for us (so long as the software doesn't rebel), thus giving us more time to devote to more interesting things. In addition, not being human, they actually seem to enjoy performing simple repetitive operations at fantastic speeds. However, some people haven't gotten wise to this and instead of using the time computers free up to actually doing something worthwhile, like thinking, they just increase the amount of boring things they can do in the same amount of waking hours.
2) I think the remote control, by making channel surfing a reality, is guilty of reinforcing the trend towards shorter and shorter attention spans. However, since getting up and walking to the TV just to press buttons is not a very exciting activity, I think on the whole it is a good thing.
3) Actually, compared to saran wrap and comic strips, the TV remote is a very minor accomplishment in the history of civilization.
What do YOU think of the TV remote? All the best, Michael Chu
dear josh starr 1) Do you think that since the television was invented children have spent less time outside and in social activities? I would guess that many kids spend too much time in front of the T.V. and not enough time in social activities but I don't have any data to substantiate my thoughts. Nobles kids excluded of course..
2) Do you think TV is too violent? T.V. is not violent at all. The shows that are shown certainly are, but I've never witnessed a T.V. being violent towards anyone.
3) Is TV different now than when you were a kid? T.V.s are now smaller today than when I was younger, but the picture tubes are bigger now. (figure that one out). They are also more often color than before. They were usually black&white. We didn't have clickers, cable or dishes picking up 1000 cannels. We only had one per house. We didn't attach Nintendo games to it. We didn't play movies with a VCR on it. And we couldn't connect to the internet with our T.V. like some are doing today. We see much more sports on T.V. today than when I was younger. I don't like very much of the programing that we see today. It's not appropriate for young sensitive minds like mine. From G Sawin
dear kellen It was invented by the right bro's in 1835 OR SOMETHING LIKE THAT Sam Stambler, Park School
I think that in the whole grand scheme of inventions, the dishwasher was probably minor. however, any invention that has become standard in the american household must be pretty important. also it created new industries, like dishwashing detergent, (which is bad for the environment). anyway, that's all i can think of. (older student)
Alexis had a home ec teacher who said that dish washers caused cancer. I think because when you wash them by hand, you get all of the chemicals off, or something. Anyway, when i took Women in America last year, we talked about the boom in technology, and the effects that they had on women. While appliances seemed to be made and were advertised to make the lives of women easier, it really caused them more work. They didn't hire maids as much anymore, and had to do all of the work by themselves. Also, if they had done washes once a week, they would do them twice or even three times, which created more work. Finally, standards were raised, and women were expected to keep the houses more clean and neat, which attached a whole set of emotional standards with housework. (Guilt, etc.) So, in that sense, the dishwasher is proably not as good of a thing. My mom also says that they probably waste energy because the water is at a hotter temperature and some othe stuff that i didn't really listen too. So, i hope i answered your question. Write back soon. (older student)
Awesome SB... I have more to add and look forward to brainstorming more on the subject of "dishwasher as menace".....consider also that before the dishwasher, there may have been a brigade of sorts, involving a few family members, one to rinse, one to dry, one to put away, etc which was probably nice family time and gave others, besides the mother, some responsibility..... (did you confuse the dishwasher with the laundry / clothes machine? sometimes I get them confused) more to come Beth Reilly
I really know nothing about the lawnmower. Hey, I don't even know how to spell it! To tell you the truth (no offense) but our whole class was forced into doing this thing. All I really know is that lawnmoeewrs cut grass. Ally Dick,Park School
I know a lot about the lawnmower. First, starting at your age or before, I had lawn mowing jobs for years. I did my fathers too and he paid me. Later on I mowed the lawn at my own home, my wife did also, for years and years. Now we have it done but we still mow at our summer place in Maine. I also have done a lot of work on various mowers from little fix ups to major overhauls. This is where I first learned about the gas engine and this knowledge has served me well not only on mowers but on outboards and other small engines as well. I have always liked mechanical things. Whats bad? I would list safety as a concern and thats about it. Whats good. Well, If you have ever mowed a lawn with the old fashioned push reel mower you would know the answer. I have and, believe me, the current day mowers are a miracle by comparison. Mr. Clifford
I am not sure what you are asking me about lawn mowers. I have used one which was gas powered and one that was electric powered. I have even used a lawn mower that was human powered (ie: a push mower). I don't mind cutting grass, but I am allergic to it. Blah. I liked the gas powered mower since I didn't have to worry about driving over the cord at all. I only had to worry about running out of gas. The push mower was perfect for my old back yard since I lived in a town house without a backyard entrance. I could leave the push mower in the backyard instead of carrying the electric mower through the house (gee it was heavy!). The push mower is okay, but you have to make sure that the blades are kept really sharp so it will cut properly.
Hmmmm.... to summarize I guess the following will do: Positives: Electric/Gas mowers - do most of the work you only have to drag it over the lawn. - you can usually set the height of the mower to control the length of your grass - with a lawn back on the mower, you don't have to rake the grass up later (time saver)
Push Mower - Doesn't use electricity or gas so it is inexpensive. - (it gives you a great workout so you exercise while doing the lawn)
Negatives:
Electric/Gas mowers - The blade area often gets clogged if your grass is moist (irritating to have to stop to fix it) - You have to pay for gas or electricity to use it. - If using the electric mower, you have to be careful not to run over the cord and make sure the cord is long enough to reach the end of your lawn.
Push Mower - You have to do the work by pushing the mower - The blades have to be kept very sharp
That is all I can think of. I hope this helps. Is it for some sort of assignment about lawn mowers? Leslie Jefford,leslie@softarc.com
Hi Nick I got your survey on submarines. Q #1 The first submarine was built around the 1860's I'm guessing.
Q#2 The first submarine worked by use of a propeller under man power
Q#3 No, I have never been in a submarine however I would like too.
Q#4 I don't know enough about submarines as you can probably tell by my answers
Q#5 The first nuclear submarine was called the Nautilus
Let me know the answers to these questions next time you mail me . Take care. I hope your classes are going well. Write again soon. Denise.
Dear Raymond, I think your questions about the space shuttle are good. The first question is kind of weird because I don't know much about it but I will try my best. I think the space shuttle is good and bad, there are many good reasons like you can studies all the different planets, you have a space shuttle that gives us tv. The bad are is there are a lot of chemicals that are deadly to the solar system and there are a lot of people that die in the shuttle when they blow up. Your Friend, Ryan Schildknecht,ltclass@pen.k12.va.us
1. I think that it's good that we have something that can be used over and over agian, but it does have some problems. 2. The major problem is that it is so expensive. It cost so much just to compleat one launch that we only have launches every once and a while. Also, the test that are performed in the space shuttle are mostly tests of the earth, or launches of new satilites. It seems the space shuttle was made for comercial purposes. I think that the highest priority should be the exploration of Mars. I know that NASA has a big plan for mars, but they should get to it, instead of all these space shuttle launches. Doug Presley,Park School
I think the space shuttle is a good thing. It should be funded by someone other than the government. Andrew Cencini '97
1. Do you think that the Space Shuttle is a good or bad thing, or in the middle, and please explain. It's good. We learn more about our environment and explore further into science. 2. Do you think that there are some problems in the Space Shuttle. Can't think of any! :) Jocelyn Huang,taurus@rgs.edu.sg,Internet
Mrs. Inman thinks it stands for "Multi O?DigitalE?Media". I think it stands for "Move Over Digital Electronic Meteors". Neither of us are close are we? Please let us know what it stands for. Kelley won't tell us what it stands for.
