13-Year-Old Uses Fibonacci Sequence For Solar Power Breakthrough
Many issues here:
(1) - Voltage is the wrong variable to measure. Energy is more relevant. He could have charged some rechargeable batteries and see how long they lasted latter with constant load.
(2) - The flat array "control", is not built in one plane facing the sun like the commercial ones. It has actually half of the cells in a second plane facing opposite the sun.
(3) - The setup is near a house wall, with the tree neared and the flat array farther, and also partly in the shade, reflected light may also confuse results. The panels should be in more controlled insolation conditions for a fair comparison.
If the kid had taken 10 minutes to talk to someone who understands solar cells this disaster would have been averted.
Doing bad science should not be encouraged !
First-of-its-Kind Hard X-ray Free-Electron Laser Images Intact Viruses
They are not obtaining images but diffraction patterns, which after applying sophisticated methods lets them reconstruct a configuration that is
consistent with the diffraction image, to within some margin of error.
This techniques tend to better for confirming proposed structures that to getting it from scratch.
New Tech Promises Cheap Gene Sequencing In Minutes
My main complaint about the movie was that ultrafast DNA analysis was unrealistic. What's next?. A device that transmits the sound of explosions in space?
NASA Finds New Life (This Afternoon)
Except that may be this saves us from deadly gamma rays from the core
Building a Telegraph Using Only Stone Age Materials
Did anyone notice the multimeter was not set to measure voltage?
The images show the ohms symbol and the beeping of the continuity detector.
Maybe it was bad editing, but as shown it seems he didn't know hot to measure volts properly.
Trojan-Infected Computer Linked To 2008 Spanair Crash
This case is interesting because from the legal perspective it is of interest to find responsibilities for the accident.
The malware did not cause the crash but it interfered with the logging protocols.
The technicians will be probably held responsible for not taking measures such as manually checking printed logs, if the computer failed.
Why Coder Pay Isn't Proportional To Productivity
To me there a good productivity indicator would be the time needed to achieve a desired functionality.
For some applications the quality of the code could be measured in terms of the computational expense of the code (does is take too much time/resouces to run).
Something harder to measure would be the maintainability. For this one could follow standardized guidelines to produce a more or less readable code.
Still there always will be intangible aspects, such as the team work previously mentioned, or coding with the goal of future interoperability.
A good coder will solve a problem fast, create code that makes efficeint use time and memory and is maintainable.
New Languages Vs. Old For Parallel Programming
I see some potential in combining innovations meant for the netbooks with multiple processors.
Low power & lightweight software may mix well with multiple CPUSs.
Design Software Giants Target the Unemployed
At the mechanical engineering level a good example would be Alibre, which is a parametric design software (like Solid Works or Autodesk Inventor).
Why Netbooks Will Soon Cost $99
I would go further and say that there's a need to revert to more power efficient devices similar to the PSION's. I submitted an idea for such at the WePC website, feel free to vote it:
