These amazing science and technology facts will give you plenty to explore if you enjoy learning surprising facts. Some facts explain how familiar technologies work and some reveal amazing facts about space, biology, physics and digital world.
Why is science and technology so amazing?
Science explains how and why things happen and technology applies that knowledge to create tools, machines, systems and solutions. The two topics are closely related.
For example, science has helped us to understand electricity . They then used that knowledge in the design of electrical devices, power systems, computers and communication technology. “Amazing Facts About Science And Technology“
Science and technology affect nearly every aspect of our lives today, from health care and transportation to communication, agriculture, education, entertainment, and space exploration.
Let’s learn some interesting facts.
1.It takes about 8 minutes for sunlight to reach Earth.
The Sun is about 150 million km away from the Earth. Light travels at the speed of light, which is 300,000 km/s. It takes 8 minutes and 20 seconds for light from the sun to reach earth.
This means that when you look at the Sun, you are looking at it more than eight minutes ago.
2.Venus’ Days Are Longer Than Its Years!
Venus has one of the oddest rotations in our solar system.
It takes Venus about 243 Earth days to rotate once on its axis, and about 225 Earth days to orbit the Sun.
In effect, one day on Venus is longer than one year on Venus.
Venus also rotates in the opposite direction of most planets.
3.There Are More Possible Chess Games Than Atoms in the Known Universe
There are ridiculously many possible chess game sequences. Depending on how the games are counted , mathematicians have estimated the number of possible games to be on the order of 10 ^ 120 .
For comparison , the number of atoms in the observable universe is estimated to be on the order of 10 ^ 80 .
This doesn’t mean that chess has more physical objects than the universe. “It demonstrates how fast possibilities can explode when you have so many different combinations.” “Amazing Facts About Science And Technology“
4.Your brain uses surprisingly little power.
The human brain is incredibly complex and yet runs on about 20 watts of power at rest.
That’s roughly the equivalent of the energy drawn by a small light bulb in a home.
Yet the brain manages memory, movement, language, emotions, decision-making, perception and many other automatic processes, all on a relatively small energy budget.
5.Computers do billions of operations per second.
Modern computers can process huge quantities of information very rapidly.
High-performance computing systems are able to do billions, trillions, or even more computations per second.
That computing power helps with forecasting the weather, scientific simulations, medical research, artificial intelligence, engineering, astronomy and much more.
6.The very first computer mouse was made from wood.
The computer mouse has advanced considerably since it was first invented.
Douglas Engelbart’s early computer pointing device from the 1960s had two wheels underneath and was encased in wood.
It seemed very simple compared with today’s wireless optical mice. But the basic idea of controlling a computer with a physical pointing device became an important part of modern computing.
7.GPS Needs Einstein’s Relativity
Your phone’s GPS system might seem like a simple navigation tool, but its accuracy depends on advanced physics.
Because of their speed and because they are in a different gravitational field, time on GPS satellites does not match time on clocks at the surface of the Earth.
These effects are described by Einstein’s concept of relativity. Engineers compensate for these tiny timing differences so that GPS positioning is accurate.
GPS systems would soon lose a lot of accuracy without these corrections.
8.Water can exist in three natural states
Water is one of the most abundant substances on Earth, but it can exist in three main states:
Ice — frozen
Water – liquid
Gas – water vapor
When water is put in certain temperature and pressure conditions, it can change from one of these states to another.
There is also a special condition called the triple point where solid, liquid and gas phases can co-exist in equilibrium.
9.Bananas are a little bit radioactive
Bananas contain potassium, and a small fraction of this potassium is naturally occurring as the radioactive isotope potassium-40.
Bananas are therefore slightly radioactive.
They are safe to eat. No need to fear them. The radiation dose is very low and potassium is a vital nutrient for the human body.
10.Your body is home to trillions of micro organisms.
The human body is host to huge populations of microorganisms, especially in the gut.
These microbes are part of the human microbiome and interact with the body in many different ways.
Scientists are researching links between the microbiome and digestion, metabolism, immunity, and other biological processes.
This is why scientists now more often speak of the human body as an ecosystem rather than a bunch of human cells.
11.DNA Carries an Amazing Amount of Information
In living organisms, DNA is the molecule that contains the genetic information.
The information is encoded in four chemical bases:
A T C G
These bases form sequences that help give instructions for building and maintaining organisms.
Scientists are also considering DNA as a potential medium for ultra-dense digital data storage.
12.Octopuses have three hearts.
PS:Octopus have 3 hearts.
Two hearts push blood to the gills and the third pushes oxygenated blood to the rest of the body.
Interestingly, the octopus stops beating the main systemic heart when swimming , one of the reasons these animals often prefer crawling rather than swimming for long periods.
13.Some Materials “Recall” Their Shape
Some materials are called shape memory alloys.
Under certain conditions they can be deformed and upon heating they recover a predetermined shape.
A well known example is the alloy nitinol, which contains titanium and nickel.
Shape-memory materials are employed in engineering, medical devices, robotics and other fields.
14.Smartphones Outperform Early Space Computers
A modern smartphone is full of processors, sensors, memory, cameras, communications systems and sophisticated software.

This is a sign of how much computing technology has evolved over a number of decades.
15.The Internet and the World Wide Web Are Not the Same
The words “Internet” and “Web” are often used interchangeably, but they are not the same.
The Internet is a global network of interconnected computers.
The World Wide Web is a collection of web sites and web pages linked together by the Internet.
The Internet can be used for email, online gaming, file transfers, messaging, and many other services without being part of the World Wide Web itself.
16.Artificial intelligence can detect patterns at amazing speeds.
Artificial intelligence systems are able to evaluate huge datasets and recognize trends that might be difficult for humans to detect manually.
Recognition of images , language processing , recommendation systems , scientific research , fraud detection , automation and more all use machine-learning systems.
However, artificial intelligence systems will not inherently understand information the same way humans do. Their capabilities are very dependent on their training, design, data and the specific task.
17.Robots Can Go Where Humans Have a Hard Time Going
Robots are increasingly being deployed in dangerous, remote or difficult environments.
Robotic systems have been explored:
Great oceans
Volcanism

Mines
The cosmos
Disaster areas
Robots can work in environments where extreme temperatures, radiation, pressure or lack of oxygen would make human exploration dangerous.
18.The Deep Ocean Is Still Weirdly Mysterious
Earth’s oceans cover most of the planet, but much of the deep ocean is difficult to explore.
Deep-sea research is hard because of the extreme pressure, cold temperatures, darkness and great distances.
Scientists study the ocean floor and marine life with remotely operated vehicles, autonomous underwater vehicles, sonar systems and specialized submarines.
19.Sound Cannot Travel in a Vacuum
Sound needs a medium (like air, water or a solid object) to travel.
Most of space is a vacuum, so there is not enough matter there for ordinary sound waves to propagate as they do through the Earth’s atmosphere.
That’s why the dramatic explosions you often hear in science-fiction movies aren’t physically accurate representations of sound in open space.
20.Space is not totally empty
Outer space is often described as a vacuum, but it’s not a perfect vacuum.
The space is filled with incredibly thin amounts of gas, dust, particles, radiation, magnetic fields and other types of matter and energy.
Some areas are much emptier than others.
21.Solar Panels Turn Light Into Electricity
Solar panels use the photovoltaic effect to convert sunlight into electricity.
When photons from sunlight strike semiconductor materials, they can help to generate an electric current.
As societies push to generate electricity from renewable sources, solar technology has become more important.
22.Lightning bolts can get extremely hot in the air.
Lightning is a huge electric discharge.
The channel of a lightning bolt can heat the air around it to about 30,000 kelvin, but the actual temperature is a function of conditions and how it is measured.
This rapid heating causes the air to expand explosively and the sound which we hear as thunder is generated .
23.Glass is a Solid Substance
Glass is often said to be a liquid that flows very slowly.
In present science, ordinary glass is classified as an amorphous solid .
Glass atoms do not have the very ordered structure typical of crystalline solids . However , at room temperature , glass does not behave like a normal liquid .
24.Some animals can grow back parts of their bodies
Animals have some amazing regenerative capabilities.
Some salamanders, for example, can regenerate lost limbs. Some organisms can regenerate large portions of their bodies.
Scientists study these animals to learn how cells communicate, grow and repair damaged tissues.
Eventually, this research might lead to advances in regenerative medicine.

Their data can help meteorologists monitor storms and track hurricanes, study cloud formations and improve predictions of weather.
Today’s weather forecasts would be a lot less accurate without satellite observations.
30.The Earth Is Always Moving
We don’t feel Earth spinning because everything around us is moving with the planet.
The Earth spins on its axis and orbits the Sun.
Earth’s rotational speed at the equator is about 1,670 kilometers per hour and its orbital speed around the Sun is approximately 107,000 kilometers per hour.
These movements are fundamental to the Earth’s day-night cycle and yearly seasons.
31.Plants Communicate by Chemicals
Plants do not communicate in the same way humans do through language but they can exchange chemical signals and respond to environmental conditions.
For example, some plants emit chemicals when attacked by insects. These signals can affect nearby plants, or entice organisms that feed on the attacking insects.
Plant signaling is a current and active area of scientific research.
32.Certain Bacteria Can Live in Extreme Conditions
Some microorganisms can survive conditions that would be very inhospitable to humans.
Some are able to survive very high temperatures, extreme acidity, extreme salinity, radiation, or very low temperatures.
Many of these organisms are called extremophiles by scientists.
Studying them allows investigators to understand the limits of life, as well as the possibility that similar environments elsewhere in the universe could support life.
33.3D Printing Makes Complex Objects Possible
A 3D printer builds an object from a digital design, layer by layer.
