Using a graph board

There is a good chance that you already know how to use a graph board based on your earlier coursework in algebra. If not, there is a series of videosbeginning at (External Link) that will teach you what a graph board is and how to use it.

Why would I direct a blind student to a video?

Of course, you may be wondering why I would direct a blind student to an instructional video. My hope is that if you need this information on graphboards, you can find a sighted friend who will help you to work through the series of graph-boardtutorials on the website referred to above.

You will need a graph board

You will need a graph board to complete many of the exercises in this collection. If you don't have access to one, it shouldn't be too difficult foryou and a sighted friend to make one using a sheet of Styrofoam, corkboard, bulletin-board material or any flat surface into which you can push pins andexpect them to stay until you pull them out.

Tactile grid lines

To create the tactile grid lines on your homemade graph board, ask your sighted friend to draw the grid lines on a sheet of heavy paper and then perforate them using a serrated tracingwheel ( (External Link) ). Then turn the paper over and pin it to the backing material so that you can feelthe perforated grid lines.

Perforating with a tracing wheel

I find that it works well to place the paper on a sheet of Styrofoam to perforate the lines with the tracing wheel. Also, some tracing wheels workbetter than others for this purpose. The serrations are very sharp on some wheels and less sharp on others. The sharp ones work best.

Using a protractor

There is also a good chance that you already know how to use a protractor to measure angles based on your earlier coursework in algebra. If not, there is aseries of videos beginning at (External Link) that will teach you how to measure angles with a protractor.

Once again, you may be wondering why I would direct a blind student to an instructional video. As before, my hope is that if you need this information,you can find a sighted friend who will help you to work through the series of protractor video tutorials.

You will need a protractor

You will need a protractor to complete many of the exercises in this collection. While it may be possible to adapt a protractor normally used bysighted students for this purpose, this will probably be more difficult than making a graph board.

A protractor that looks like the one in the video can be purchased at (External Link) . However, this is not a recommendation that you purchase this particular brand ofprotractor. You should do your own shopping and make your own decision.

JavaScript programming

As I stated earlier, you will need an introductory understanding of JavaScript programming ( (External Link) and (External Link) ) to work through the exercises in this collection of modules. Why is that?

Incompatible typesetting elements

Typical physics textbooks designed for use by sighted students are full of typesetting elements that are often incompatible withaccessibility tools such as screen reading software, a Braille display, or both.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
