Asad Mehmood’s out-of-this world dream

There are people though, who do not have access to half the resources I do in Pakistan who do not give up. Asad Mehmood is such a guy. He hails from Okara and at the tender age of 18 built himself the 6th largest telescope in Pakistan

The first time I gazed at the sky in fascination was on a clear night on an off-road trip in Hingol, Balochistan. I had never seen a sky so full of stars and stood awe struck at the beauty and magnificence of the heavens. Naturally, my next impulse was to buy a telescope powerful enough to see them up close. I found this to be a very costly venture as telescopes, especially good ones are expensive. So I proceeded to scrounge for details on how to build one on the Internet.
When I discovered that building one requires an array of optics not easily found and of considerable expense, I gave up this pursuit as well. There are people though, who do not have access to half the resources I do in Pakistan who do not give up. Asad Mehmood is one such guy. He hails from Okara and at the age of 18 he built the 6^th largest telescope in Pakistan. This guy is super cool – here’s The Express Tribune magazine story on him.
How did he do this?
I caught up with him at a local event to ask him just that! Readmore Asad Mehmood’s out-of-this world dream

It appears that not anything strikes fear in the hearts of students and parents like these three words: science fair project. But it doesn’t have to be that way. A science fair project is an chance to research and learn about things that notice you. And through your studies you will learn how science is essential to everything around us. You will advantage beyond your improved science knowledge. Science fair projects teach you problem-solving skills, improve your written and oral communication skills and give you the satisfaction of completing a well-done project. The ideas for projects are endless; you are limited only by your imagination. For example, does dirty dish water affect the growth of plants? Or how does acid rain affect plant growth? Which diapers are the most absorbent? What is the pH of various shampoos? Do different brands of gasoline make a difference in gas mileage? The first key to…

Make Heron’s Fountain

    Science Fair Project: Make Heron’s Fountain Heron’s fountain is a great project for a science fair, as it is simple to make and displays many of the basic principles of physics. This project shows how potential energy can provide power, using water and gravity, and air and compression. These are fundamental aspects of pneumatics and hydraulics and Heron’s fountain also lets you have a bit of fun during the process. The History of Heron’s Fountain Heron’s Fountain (Creative Commons) The great Greek inventor, Heron of Alexandria (sometimes called Hero) created this device as one of his wonderful ways…

Archimedes Displacement Experiment

Archimedes Displacement Experiment Science Fair Demonstration The Ancient Greek mathematician, Archimedes, is most famous for running naked down the street shouting ‘Eureka! Eureka!’ (I have it! I have it!), after finding out the solution to a tricky problem.   While he contributed much more to science than this, including building the foundations of the study of hydrostatics (how fluids behave), and writing volumes of work on the properties of solids, his famous experiment is perfect for a science fair demonstration. Why Did Archimedes Shout Eureka Submerged and Displacing Cylinders (Public Domain) King Hieron II of Syracuse had commissioned a goldsmith…

Build an Astrolabe

Build an Astrolabe Science Fair Projects The astrolabe is an ancient device, long used to measure latitude and act as an aid to navigation. Historians believe that the first astrolabes were devised by the Ancient Greeks, with astronomers such as Apollonius (c. 262 BCE – c. 190 BCE) and Hipparchus (190 BCE – c. 120 BCE) developing the theory behind the device.

Double-Angled-Twelve-Sided cooker

Double-Angled-Twelve-Sided (DATS) Solar Cooker (Editor's note: SCI has not tested this cooker for safety, effectiveness, stability, or ease of use) by Teong H. Tan I was introduced to the world of solar cooking in 1982 when, as a student, I was working on a heat-transfer experiment at the Brace Research Institute in Montreal. Brace had shortly before that experimented with and tested a variety of solar cookers. Many years had passed by for me without any further solar cooking exposure until I discovered Solar Cookers International’s web site three years ago. The site has since become the place where I…

Magnetic Levitation Science Project

 

description

Here is a very cheap and high stable levitation schematic for beginners it uses only to transistors and few other parts they are all easily available in hole world instead of those pricey and complicated integrated IC schematics take hole day to built but this project is not only cheap but easy to built in minutes coil is made in this project from scrap I took primary winding wire from an old wall mount 12v power supply and Use sewing machine bobbin for coil winding there is no counting for turns just make sure wind bobbin full until it reaches its outer radius secure it with electrical tape make sure both ends of winding are enough length to solder it to project board use bolt as core which fits in bobbin hole make sure bolt must be twice in length than bobbin so that you can nicely tighten your coil to frame for further info see fig2.
