A little eBook on Beneficial Viruses

Beneficial Viruses - When Villains become Heroes
“Beneficial Viruses – When Villains become Heroes”

A little eBook of mine “Beneficial Viruses – When Villains become Heroes” has been published on Amazon Kindle…

It has been written in a way that is fictional and non-fictional at the same time. It has 26 pages, so it would not take much of your time, but it will surely give you a huge amount of information.

You can check the book here:

NASA’s Mars rover Curiosity has recently sent an interesting image of Mars showing a “floating spoon” type of thing on the planet. This floating spoon looks like hovering above a ridge with a shadow on the surface. Continue reading Curiosity’s finding of strange “floating spoon” on Mars

Photography – an art, a science, and a job

Main Points:

Photography is an interesting task that inspires many people to inspire many others. It starts from the art of creativity and imagination, goes from the science of click and light, and ends with a beautiful memory in the hand or book. For some people, this memory helps them in earning more memories.

So, one of my favorite ideas to earn more memories is through Dreamstime. You can join Dreamstime to earn money and help others to earn money through photography, here:

Study Further:

Photo is a representation of a person or scene in the form of a print or transparent slide. It is recorded by a camera on light-sensitive material. The process of taking photos is known as photography. It is a science and art, and immediately after the invention of this process, it became a kind of job too.

Photography as an art

“I like photographs which leave something to the imagination.” – Fay Godwin

Photos help us to capture beautiful and unique moments in our life. They can make us laugh and they can also bring tears in our eyes. They can remind us of our past and they can inspire to do something great in our future. They make us creative and imaginative. A simple idea for creative photography is “Imagine novelty”.

Remember, “The camera is an instrument that teaches people how to see without a camera.” – Dorothea Lange

Photography as a science

“Photography is putting one’s head, one’s eye and one’s heart on the same axis.” – Henri Cartier-Bresson

Physics and chemistry is also involved behind the science of photography. Cameras for photography have lenses with particular focus and aperture. Light is involved in capturing those beautiful moments. Photography is also related to science in many other aspects as, for example, scientists have found that learning a new and mentally demanding skill such as photography can help in improving cognitive functioning (Park et al., 2013). In another study, scientists found that (edited) photos can manipulate our memories (Sacchi et al., 2007).

Photography as a job

“It is a beautiful thing when a career and a passion come together.” – Anonymous

Photos can also help us in earning money. People can make a good amount from photography. They adapt the profession of “photojournalism” or work as freelancers.

In the present technology of internet, it is easy for anyone to sell his or her photos online. Many free stock photo sites are available on internet and some of them are Dreamstime, Shutterstock, and Fotolia. You can join these sites and start earning by selling your photos and images. Interestingly, you can also make money by referring other people to these sites. One of my recently explored sites is Dreamstime.

Thoth Technology, a Canadian tech company, has recently filed a patent for a 12.4 mile high (i.e. about 20 kilometer tall reaching the stratosphere, and about 20 times higher as compared to Dubai’s Burj Khalifa) “space elevator” that can become an alternative to rocket for astronauts, i.e. this invention will help to launch astronauts as well as tourists into orbit.

According to the patent of the company, it will be an inflatable, pneumatically pressured tower having a liftoff point (platform to launch) to space at the top. According to the company, this invention will help to save over 30% of the fuel of a conventional rocket.

“From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight,” stated Brendan Quine, who is the inventor of the ThothX Tower.

This invention will help to launch the rocket in a horizontal manner by removing the requirement for vertical launch, i.e. flight will be much like a passenger plane.

“In our concept, you ascend electrically and remove the whole vertical launch phase,” Quine stated. “Then you get into a space plane, which is like a passenger jet, and take off horizontally.”

This tower will serve not only for the launch of astronauts but it would also help in the generation of wind-energy, scientific research, communications, and tourism (as told earlier).

It is still on the paper but patent is showing that the company has moved a step to bring the physical product.

Detection of Alzheimer’s disease with a digital pen

Alzheimer’s disease is a degenerative brain disorder that is similar to senile dementia except that it begins in the later stages of life, usually after 40 years. Among the first signs and symptoms of the disease are impaired memory along with impaired thought and speech. However, these signs and symptoms appear after a significant damage to the brain.

This disease (along with many other psychiatric problems such as Parkinson’s) can be detected by doctors and experts with the help of drawing and/or writing. However, doctor’s or expert’s opinion matter a lot in detection of such problems, and these problems become apparent only when the patient has already advanced to serious conditions. Without an expert’s opinion, it is difficult to confirm the problem.

Recently, MIT researchers have developed a digital pen that is attached to a custom tracking software. This digital pen can help in finding the condition in early stages by knowing not only what the person draws but also how he/she draws an image or diagram. A simple fact is that healthy people spend more time in thinking, whereas people with memory problems spend a lot more time in thinking and patients of Parkinson’s disease struggle with the process of drawing.
