A Few Recognized Books On Science Fiction

Among different reading genres, it’s the science fiction which tops the acceptance charts. After all, the action and the attention aspect of the science fictions may easily make them a must read. There are many books that make use of science fiction as their background to capture the attention of the readers. However, there are many others which are pure science fictions too. Let’s have a look at some of the must read science fiction books.

‘Dune’ is most likely the first name that comes to any sci-fi enthusiast’s brain when speaking of top science fiction. Written by Frank Herbert, this book is considered by many to be the best challenger to the additionally legendary ‘Lord of the Rings’ by J.R.R. Tolkien. In fact, many critics have labeled the book as ‘the pinnacle of literary achievement’ in the realm of science fiction writing.

The next in line book on science fiction that could win over you no ends is Snow Crash. This book is best for all those who are fond of cyberpunk genre. The main figure of this book is a boy who has various shades in his figure. He multitasks as a pizza delivery boy, as a part time hacker and as well as a samurai swordsman. This book as written by Neal Stephenson is filled with action ‘n thrills that is surely going to leave the readers gripped.

Are you searching for a book that’s somewhat like Matrix? In case yes, then Other land by Tad William is all that you need. Unlike most sci-if books that are more about blabbering and less about action, Other land offers you action in every line. Though the book begins on a a little sluggish note, it eventually picks up as you read it through.

Endear s Game by Orson Scott Card is another sci if book that’s 1 of its kinds. This book mixes human emotion along with science fiction and makes for a compelling read. The book is concentrated on the tale of a boy who is all set to protect the fate of humanity. The boy’s never say die philosophy amidst heaps of sci-fi drama makes this 1 a must read.

Last however not the least; Forever War is an additional book that can support satiate your search for a good science fiction. However, it is suggested to read this book only in case you are pretty habitual of reading a science fiction. In case you are a newbie, it appears reasonable to stay clear of reading this complex sci fi. This book has some very powerful action sequences that could become pretty repelling at times. However, the first attempt of the author Joe Haldaman is always to disseminate around the idea about futility of a war.

So, what are you waiting for? Opt for your pick and you are certain to like the fiction and the drama that all these books may provide.

The Principle Of Retinal And Iris Scanning Technology

Fingerprint method can be misapplied. This reality is proven scientifically correct. For that reason, people then try to find the more reliable biometric systems.

The retina is part of the eyes that is responsible for the ability to see. The pattern of blood vessels that forms the retina is as unique as fingerprint. The principle of retinal scanning technology is scanning the pattern of capillary blood vessels on the retina with low-intensity light sources.

In 1987, the first retinal scanner was made by Leonard Flom and Aram Safir and has been patented. However, by the year 1994, John Daugman developed the technology of iris scanning as a competitor for retinal scanner.

Retinal scanning principle

Retinal scanning is based on the fine capillary network that meets the needs of oxygen and nutrients to the retina. These blood vessels absorb light and can easily be visualized with appropriate lighting. To that end, the close distance between the eyes and a scanner is needed. The appropriate position of eyes toward the scanner is also necessary. Also, there must be no eye movement, such as blink or glance.

Retinal scanning can not be 100 percent accurate. It is also less suitable as a security tool because even though the pattern of capillary blood vessels of human beings’ retinas cannot change generally, but diabetes, glaucoma, and cataracts can change it.

Iris scanning

In its development, retinal scanning is considered to be too disruptive in the case of security detection devices. In the use of retinal scanning, the eyes should be as close as possible with the scanner. For long-term, the light of scanner that is too close to the eye can give negative effects.

Because of the weakness, iris scanning technology emerges as strong competitor. Iris, a network that gives color to the eyes is also unique in which the chance for two identical slices is 1:1,078. Even, the left iris and right iris of someone are different.

The Science Behind Writing a Mystery Novel

When beginning to write a mystery novel that has police investigations it is important to understand that there will have to be some science in the story. You may disagree and say that it is not absolutely necessary, but if you want to sound professional, and be logical you want to incorporate at least a little bit of science in. This can establish credibility and the more experienced mystery novel readers will appreciate this.

The first thing you want to do is determine what science exactly you want to incorporate into your novel. It could range from something like DNA fingerprinting to cloning. You do not have to choose only one topic either, it keeps the story more interesting if you include a collection of different forensics for your readers. This also allows for more wiggle room when starting to write your novel as well. If you have more science, the story is easier to work with and build around. It may even provide inspiration when you are going over what topic you want to choose.

When you are choosing what science subject you want to involve in your story it is good to choose something that is more unique and maybe not commonly heard of. This is not the case the whole time, but it could provide for a more interesting plot. Remember you want something that is interesting, accurate, and modern. It must make sense to the reader, and it helps if the science is more up to date or even futuristic, as long as you can explain it and it is true, you have a good science topic.

After you decide what you want, it is time to research! There are many resources you can find on the internet that will supply you with valid and useful information, although you want to be careful when picking and choosing what is fake and what is true. It would not be good to be caught having false information in your story when you believe it is true. There is a way to avoid that situation though. There are books out there that offer information that works perfect for this, or sometimes there are even books made specifically for that. One book that does this is called Murder by Proxy. This will help you get all the scientific part of the plot, so that you can focus on the story writing.

Overall the science behind a mystery novel is important, simply because not only will it make your story more intriguing, but it will also appeal to the more knowledgeable novel readers. If you can add in science into your tale, you are well on your way to writing a great mystery novel.

Science Experiment How To Make Invisible Ink

Invisible ink has been used by spies and secret lovers alike for centuries to transmit hidden messages to their partners. Invisible ink isn’t just something you see in James Bond movies; hundreds of liquids, from fruit juices to household liquids, to specially formulated chemicals, can be used as invisible ink. In this science experiment, become a master of “steganography” by making your own invisible ink from baking soda and send secret messages to your friends:


“Purple grape juice
“Baking soda
“Tap water
“Cotton swab
“White writing paper


1.Thoroughly mix equal parts tap water and baking soda powder in a container until dissolved.
2.Use a cotton swab or fine paintbrush to write a message onto the white writing paper, using the baking soda and water solution as invisible ‘ink’. Make sure to dip the swab into the “ink” often so that the recipient can read the message with ease.
3.Allow the “ink” to dry out thoroughly until the writing becomes completely invisible. Your secret message is now ready to be delivered to the intended recipient.
4.One way for the recipient to read the message is to hold the paper up to a heat source, such as a light bulb, hot iron or it can even be placed in an oven. The baking soda will cause the writing in the paper to turn brown to enable the recipient to read the message!
5.A second method to read the message is to paint over the paper with purple grape juice. The message will appear in a different colour!

This science experiment works because substances such as vinegar or baking soda are either mildly acidic or alkaline, and such an acid or base weakens paper. The base from the baking soda remains in the paper after the water has evaporated and the paper has dried. When the paper is then held near a heat source such as a light bulb or hot iron, the alkaline parts of the paper burn or turn brown before the rest of the paper does, revealing the message written on the paper!

If you are using the grape juice method to reveal the message, the baking soda and grape juice react with each other in an acid-base reaction, producing a colour change in the paper to enable the recipient to read the secret message. Grape juice concentrate results in a more visible colour change than regular grape juice. There are many other household liquids that can be used to make invisible ink. Using the heat method, you can also use white wine, vinegar, apple juice, and even milk!

It has achieved the same level of the E-ink screen for long reading time.C-paper technology should be regarded as a kind of technology to optimize the screen’s backlight.


E-ink and C-paper
Based on C-Paper and E-ink screen technology has the same eye protection function, while the performance in color and screen response speed far beyond the latter. In power consumption, the battery life has reached more than 50% of E-ink, up to 12 hours continuous reading time, pages 3500 or more, fully meet the needs of daily use.

The advantages of C-paper technology in color display, visual effects, long reading time, screen response speed are over E-ink. In addition, eye protection function is comparable with E-ink.

The differences between C-Paper screen and E-ink screen is their power consumption.Flying power of C-paper screen is half of E-ink’s.And visual effects in bright light for E-ink is good. But people spend no more time reading under the glare like the sunlight. If they want to read in dark, C-paper screen ebook reader is the best choice,while E-ink screen ebook reader failed. As to the thickness of screen, C-paper’s is thicker than E-ink’s because its back light module whithin.

These are the comparison of C-paper screen and E-ink screen from which we can discover that,although the weakness of C-Paper screen is power consumptive,it also features so many advantages over E-ink screen.

Zoology Science Fair Projects

Among the topics of interest for students who wish to create zoology science fair projects those that involve ants are the ones most students will choose. A zoology science fair project will demonstrate the knowledge that students have learned regarding some particular type of animal. Ants hold a great fascination for children and adults alike. These amazing little creatures are communal and depend on each other for survival. Very seldom do we see a single ant. This type of living system makes ants a favorite topic for zoology science fair projects. Students can choose any number of subjects related to ants or any other animal to study for their zoology science fair projects.

One of the most interesting subjects that students study using ant populations is in the area of food choice. While most people are familiar with ants as uninvited guests at picnics, most people know very little about these tiny creatures. A zoology science fair project will use different foods to see which flavors, if any, the ants prefer. Students will conduct experiments and collect the data from these experiments in order to make a presentation for the zoology science fair projects. This data will then be used to compare different types of foods. It could then be used in supplemental studies to compare the flavor choices of different types of ants. These little creatures are more than willing to participate in these types of experiments because all that is required of them is that they eat!

Zoology science fair projects can also be performed on microorganisms such as bacteria. The zoology science fair projects can also be based on the osmosis and diffusion that is present in living cells. These types of zoology science fair projects are particularly suited to computer-generated presentations. Since these organisms and processes are too small for the human eye to see, students often have a difficult time grasping the concepts. Zoology science fair projects are a great way to demonstrate these types of scientific phenomenon. The presentations bring to life all the tiny components involved in the life experiences of living creatures. These and many other topics, such as the study of environmental changes for marine life, the effects of chemicals on animals, and how different conditions affect growth rates, can be explored with zoology science fair projects.

Why schools must invest in good quality school science lab supplies

The reasons for having good quality and latest science lab supplies in schools are innumerable. Science labs help develop the interest of students in science and related subjects. They encourage students to investigate and understand the things that make up the world around them. Be it the weather, the environment, the food that they eat, the animals and plants that surround them, the various resources that they use for getting heat and light, and the functioning of their own human body, school science labs promote knowledge and awareness about science amongst students.

School science labs prepare future scientists and research scholars. Most dedicated scientists and researchers develop their life long interest in the particular field in their school science labs, as soon as they perform their first science experiment. In the absence of proper school science lab supplies and science laboratory equipment, schools canno prepare next generation scientists, engineers, and doctors.

Most medical and engineering colleges and universities require students to have completed necessary laboratory courses for getting admissions. Students get first-hand experience of using various basic science laboratory equipment and tools which eventually prepare them for advanced study in the field of science and technology.

Considering all these factors, it becomes imperative for schools to buy essential school science lab supplies.
