National Weather Service Radars

The National Weather Service is responsible for keeping track of the weather patterns, trends and current conditions in the United States. To do so, there is a large network of National Weather Service radars that help gather this information. From the radar images, data is interpreted and updated constantly to keep all information current.Experts whose specialty is to interpret the data monitor the National Weather Service radars. They then publish some of their images and findings on...

Static Neutralizers

Normally atoms have equal numbers of Protons with positive charge and Electrons with negative charge. This parity is upset when an electron sometimes moves to another atom because of friction, pressure or induction, and leaves the parent atom with a positive charge, or "ionized". The energy that emerges thus remains stagnant until it is earthed or otherwise neutralized or an electrostatic discharge (ESD) takes place. If the charge builds up and the ESD is severe, it could have serious consequences...

DNA Testing Services

DNA testing centers provide service-oriented DNA analysis for determining biological relationships through DNA paternity testing, DNA genealogy and anthropology testing and sibling DNA testing, and other peripheral services like DNA banking and ID services and DNA detective testing services, among others.DNA paternity testing is the most popular genetic testing service, and helps in establishing the paternity of not only a child but of an unborn fetus. Most DNA paternity tests are 99.9%...

What Is A Fossil?

What is a fossil? While this is a simple question, the answer can be simple or a bit more complicated. The short and sweet answer to that question is "A fossil is the remains or evidence of any creature or plant that lived on the earth in a past geologic age." But there are so many KINDS of fossils. A more important question for a curious student is "What kinds of fossils are there?" The answer to that question will take a bit more exploration. You'll have to dig a little deeper...pun...

Sundails: Do they Really Tell Time?

Sundial HistorySundials have been around since the days of the Sumerians, some five thousand years ago, and were the earliest known means of keeping time. The first sundials were probably just rods or sticks pounded into the ground, and the shadows cast by those vertical rods (called a gnomon) allowed ancient people to know what time of day it was.The Greeks and Romans took the basic concept and refined it, using various different shapes of dials to not only tell the time of day, but also...

Quartz Clocks and Atomic Clocks

Ole! - we are finally there. Little by little we have arrived to the "today's clocks".Even though the quartz clocks were created around 1925 - we still use them today. The clocks were built with quartz crystals. They work like this: a battery sends electricity to a crystal which vibrates; the vibration sends out evenly spaced and very rapid electric signals that measure the time and control the clock display. The early problems with the quartz clocks were that the crystals were affected...

Atomic Clocks: Why They Are The Best

A common problem with many clocks is that there are times when they may be wrong. Hundreds of years ago, time did not need to be as accurate. If you are minutes late today, that could put your job in jeopardy. Modern technology has answered this problem with the most accurate time keeping possible. Scientists have used atoms to find a consistent way to keep time. They have also made this information available so that civilians can use it as well.Atoms have a constant oscillation frequency...

Types Of Telescopes For Astronomy

Basic Telescope DesignsThe job of a telescope is to collect light, not to magnify an image (the eyepiece does that job). The larger the objective (the part that collects the light) whether it be a lens, in refractors, or a mirror, in reflectors, the more light the telescope will collect. The more light you can collect, the more detail you will be able to capture, and also important for astrophotography, the shorter your exposures will need to be to capture this detail.Refractor TelescopesThe...

NASA Astrobiology Cuts Are Unfortunate

It is truly unfortunate that NASA is cutting its astrobiology research divisions down to a minimum as if we are truly going to explore the Universe with human manned space exploration vehicles and research teams we will need to know as much as possible about what we are getting into. So if we go where man has never gone before and boldly so, we may find our selves SOL when things go wrong, without the knowledge that the teams and researchers at the NASA Astrobiology Labs can bring to the...

Your New Dish Network Satellite Receiver - What Is It?

Your new Dish Network digital high definition satellite receiver is the single most important piece of equipment in your home entertainment system. This is the 'enabler' for signals to be received from Dish Network's fleet of nine satellites in orbit around the Earth and transmitted into your home. Dish Network offers more in the way of home entertainment than any other satellite provider, and their ever-growing subscriber base of 12 million attests to this fact. Satellite television...

Secrets of The Mathematical Symmetry of Nature and Patterns of Erosion

As scientists and theorists study patterns, design, chaos, complexity they often turn to nature for examples and there is plenty of examples in nature too. The stripes on a zebra, patterns on a butterfly, spider webs, leafs on a tree, scales on a fish, seashells, brain waves, muscle structure, texture of granite, spider webs, Earth cycles, waves on the ocean, wind flow, clouds in the sky, Rainbows, Solar System, structure of a meteorite and even DNA itself.One pattern of nature we often...

Things You Need To Know Before You Buy Your HDTV

If you are in the market for a HDTV you probably are somewhat confused by all of the terminology used in the industry, but actually it doesn't take too long to learn your way around, and be an educated television consumer. When looking for a HDTV, you will no doubt run into a couple of terms that you will need to understand very well. You will see a TV labeled as "HDTV Enabled", and then you may see others labeled "HDTV Ready" or "HDTV Integrated". There is not usually much difference...

Training Plant Growth Acoustically

Have you ever walked down a sidewalk and the sidewalk seems to make a little jump, which would not be much good for anything unless you were a male youth with a BMX Bicycle or were just kicked out of the shopping mall on your skateboard for doing tricks? Most of us have and we know that the roots of the trees have uprooted the sidewalk. Recently some studies have been done which used directional acoustics to train root growth. No the application was not to protect sidewalks or protect the...

Building an Ice House on Mars

There is ice at the Martian Poles, one of the poles has water ice in abundance. Such an ice over region could easily be converted into a habitat for a Martian Colony of human explorers. Taking humans to Mars is not such an easy task, keeping them alive once there even harder, bringing them back not easy at all. The polar water ice cap may hold the key to building a successful colony on Mars.Do you remember the James Bond Movie that took place as the ice hotel? There is actually a place...
