Ever since the beginning of our human saga, many people came up with ideas, beliefs, experiments, and inventions to make our lives more exciting and comfortable, and why not, give us a little more sense.

These genius minds and their passion, dedication and immense hard work have reshaped the notions we have about the world around us and have helped us as a community discover some of the laws of reality. And to celebrate that, let’s learn more about the greatest scientists who have ever lived.

Marie Curie is legendary

We’ve all heard the name of this physicist and chemist too, but how many recall Marie Curie’s contributions to the world of science? The Polish genius studied at the Sorbonne, where she immediately became the head of the physics lab, which was a rare thing for a woman to do in the early 1900s.

Sadly, this is true even today. She also holds the record for the first female to receive the Nobel Prize, and she is one of the few to have it awarded for more than one category. This is why she has always remained a source of motivation and inspirations for women of all social backgrounds.

She created the first mobile X-ray machine, a fantastic tool which helped injured soldiers on the battlefield. Radium is another great discovery of hers. Although, with all her brilliance and hard work, the discovery still killed her, as she died of radiation poisoning in 1934.

 

Isaac Newton was quirky

Sir Isaac Newton, an indisputable amazing human, was born in 1642 and died in 1726. He was a polymath and made investigations into a whole spectrum of subjects including mathematics, physics, astronomy, and optics.

In his magnum opus, called Principia Mathematica and which was published in 1687, he alone laid the foundations for what we refer to as classical mechanics today, and there he also explained the laws of gravity and motion.

The scientist showed that the same set of natural laws governs the motions of objects on Earth and on celestial bodies, which radically changed the way humans viewed the natural world. Newton enunciated the core principles of conservation of momentum and of angular momentum too.  

Albert Einstein’s legacy still lives today

Albert Einstein was a famous German-born physicist. He famously developed the most celebrated and accurate theory of general relativity, which is one of the main pillars of modern physics. His equation E=mc2 is known by many, although few people understand what it means.

In late 1921 he was awarded the Nobel prize in Physics, mainly for his discovery of the law of the photoelectric effect. His simple equation eventually led to the creation of the scary atom bomb, which some say he regretted. Einstein also helped develop the delicate theory of quantum mechanics and subatomic particles.

These are just three of the millions of minds who have contributed to us getting to the point where we are today. Many more scientists are waiting to be discovered, and you should research which geniuses have created the things you enjoy the most in this world, as an ode to brilliance.

 

 

Stephen Hawking was a scientist mostly known for his discoveries in the cosmology field, and his most famous revelation was when he proved, using the complex quantum mechanics, that black holes do indeed emit radiation, which shook the world of astronomy.

Hawking is also cherished in popular culture for his book A Brief History Of Time, a nonfiction novel which can be described as simple and straightforward yet very educative. But that is not his only creation, as he wrote many books besides that. This article will try to offer you a starting point to his body of work so you can enjoy his genius too.

 

Start with A Briefer History Of Time

This book can be a suitable place to start his literary works if you know very little about the things he talks about because it is the ridiculously simplified version of his better known-book. While reading it, you might have to do a little bit of research to understand his mind-blowing ideas entirely, but overall, it’s a very digestible book.

You can’t really go wrong with this starting point, because the piece is short and it’s meant to be super accessible to the general public and to young students. It can be a way of testing to see if you enjoy his writing style and if you agree with some of his more radical ideas.

 

Continue with A Brief History Of Time

His work is about more than explaining physics and quantum theories. A Brief History Of Time will offer you an introduction to the nature of time, the strange and unpredictable behavior of particles, and even to black holes. But ultimately, it’s about existence itself.

More specifically, Hawking was trying to answer a question posed by Einstein, which is how much did God, if he exists, contribute to the creation of the universe? It too was written with non-scientists like us in mind, because he considered scientists already have access to hundreds of sources of information, and he wanted the public to enjoy astronomy just like he did.

 

Finish off with all the other books

There’s one obvious place to reach to after reading Hawking’s A Brief History Of Time, which is Black Holes and Baby Universes and Other Essays, published in 1993. It is ideal if you’re feeling a bit confused by black holes because he talks about them from a fresh perspective, and you will for sure learn a ton of new stuff with the help of the book’s simple language.

The Nature of Space and Time could be another one of your lectures. It takes the shape of a series of debates where Hawking and Sir Roger Penrose discussed physics and philosophy on an epic scale. And if you really got a taste of his work, you’ll be happy to hear that he has many other books available for you to explore.

 

There’s hardly a more lovable and a more exciting science popularizer on TV right now. Neil is one of those rare finds, one of those humans that you can’t help but be mesmerized by. And with the reboot of the amazing TV-show Cosmos, he has solidified his legacy as one of the smartest and easiest to follow astrophysicists of today. And to discover this mysterious character, we have compiled a list of interesting facts that you might not know about his life and career.

He is known mostly for his TV appearances and for the fact that he became an Internet meme that has swiped the Internet. However, fewer and fewer people know that he is the head of the Hayden Planetarium. Not only that, but he is also an associate of the American Museum of Natural History, where he contributes to research at the Astrophysics department. He is one of the few ones that seem to have time to do it all, and to do it well at the same time.

Neil was born in Manhattan, where he has a modest upbringing. His mother was a gerontologist and his father a sociologist, so it’s not hard to see where he got his analytical abilities from. Ever since a young age, he was interested in astrophysics, but also in sports like wrestling and football. This duality is not common among the intellectual elite, and it is not a wonder why he described himself as a “nerd who could kick ass.

And his passion for space didn’t go unnoticed. He was invited for an undergraduate program by Dr. Carl Sagan himself, one of the most amazing humans that have ever lived, and also the guy who also sparked the interest in space in so many young minds with the original Cosmos. But despite that honor, he chose to go to Harvard, where he got a major in Physics. At the same time, he also took time to pursue his other passion, as he was often seen rowing, dancing, and even wrestling.

Regarding his career, he focused on stellar evolution and cosmology, and he is even cited as the 18th author on a paper that later won the Nobel Prize. He wrote many popular books which have brought the public closer to the science of space, and for his advances in theoretical physics and his work with the American Government, he was awarded by NASA the Distinguished Public Service Medal.

One of today’s most respected scientist, Neil deGrasse Tyson is one to watch for now that the second season of Cosmos is in the works. His voice is not impossible not to recognize, and his knowledge and research made sure that he gets to stand in the hall of fame of the humans that propelled our species into the future.

 

On my cereal box, I once found a very inspiring quote from Confucius who said: “Choose a job you love, and you will never have to work a day in your life”. I guess finding the right job will be definitory for your future life, especially if you want to have a happy and fulfilled one.

But how do you find the thing that you’re good at and also gives you pleasure? Most people go to college, follow Masters’ programs and, after a lifetime of studies, are still not sure what to do. Others are luckier and find the right path in life from the beginning, sparing years of useless studying and things they’ll never use.

Although most of us love animals, not many would consider making a true job out of this. We all had pets or still live with some, but how many of us did we really consider pursuing a career in looking after pets? If you think this is your one true call, here are some suggestions I reckon are great as a starter.

Dog Walker

You may not earn a fortune, but this will certainly test your limits and make you truly bond with dogs from all kinds of environments. Consider this your entry-level job if you want to pursue a career in helping animals and not just keep them in Gerbil cages.

The good part is that you won’t require any special skills, diplomas or degrees and you can earn an extra buck while paying for school or trying to figure out your next move. The downside is that you’ll probably need another job to deal with daily bills and the costs of living a decent human life.

Veterinarian

The most obvious choice for many who love animals is becoming a veterinarian. And even though plenty of kids dream about doing that when they grow up, just a few actually manage to graduate the university and practice as veterinarians. It takes a lot of years to study and even more years to practice until having a steady hand.

The perks of the job are countless and you’ll be able to put a smile not only on an animal’s face, but also on their owners’. The downside is the cost of the university, not to mention the additional costs of tools, books, practice, and more.

Marine biologist

If you love the sea and everything related to it, then you should consider becoming a marine biologist. It takes a certain school and great diving skills, but you get to see the most beautiful fish in the world and interact with dolphins, whales, and even studying their behavior. It is a great opportunity to indulge in your passion for exploring wildlife while still adding a contribution and fighting against excessive water pollution and hunting endangered species.

 

 

 

Do you have a multimeter in your toolbox? I had no idea I needed one until I started fixing things around the house. It was then that I learned that I should purchase a multimeter. No matter what you do, from mounting a new fan onto your ceiling, to any other kind of electrical task, you need to know if there is electricity on the wires.

If you don’t know such a thing, accidents can happen. It can be very dangerous to work with electrical fixtures and wires, as you can get electrocuted. A multimeter will provide you with essential information on the electric power flowing through the wires, expressed in volts, amps, and ohms.

It is not only you who is in danger of injury or worse. Anyone in the house who may touch the exposed electrical wires by accident will be exposed to the same risk. Also, electrical short-circuits can be responsible for fire hazards, and that means that a fire can break out without your knowledge.

 

 

Things you can do with a multimeter

Testing batteries – you can use your trusty multimeter to test battery life. Since you can troubleshoot any electrical device using one, you just need to see what the readings tell you when you check your batteries. You will notice that the reading lets you know the battery voltage; if that sits at less than 20%, the battery is depleted and you should replace it.

Testing broken cords – extension cord may bend, and break and exposed wires are a real hazard for one’s life. By checking the wires, you will know if the cable is still safe to use or not. If the reading on your multimeter is “0.00”, that means that you are dealing with a closed circuit. The “0.L” result indicates an open circuit.

Testing appliances around the home – the same readings as before apply. This is something you must do when you suspect your blender or any other device in your kitchen and home to be defective.

 

Safety above everything else

You should always take the necessary precautions when you’re testing electrical wires and devices. That includes as a basic rule to have the power disconnected. Keep in mind to handle the multimeter by its handles, which are insulated and will not allow electricity to be transferred to your body.

These are a few things you should know about owning a multimeter and how to use it. Household appliances can break down, and there are situations when you need to fix things that involve electrical power. To deal with them in perfect safety, this is the type of tool you should get for your home.

 

 

 

 

Nothing’s more complicated than choosing a new telescope these days, and that’s because there are just too many choices to consider. On the one hand, not all are made the same and so they’re not suited for the same purpose. On the other, there are price differences to consider, constructional quality details, as well as convenience and ease of use, and they all need to be mulled over before making a final call.

 

There are three main types of telescopes you ought to make up your mind on. Refracting telescopes are more affordable than their counterparts and that’s because they are more prone to color aberrations and others. The quality of the image is somewhat lower compared to that which can be ensured by a reflecting telescope. Both the material that the latter has been made out of is better, but it’s also beneficial for a number of other reasons. For example, reflectors are large, which means that they can collect much more light and make it possible for you to glance at a brighter and clearer image.

Cassegrain telescopes are others you ought to take into account. They combine the advantages of reflectors and refractors and still have a somewhat portable design that can allow you to take them where your adventures might take you.

I’d like to add here that one of the core parts of your research should be going through the reviews of other buyers. You need to read a buying guide to make sure that you’re focusing on the right factors such as the aperture and other capabilities and features.

I needed to look at the amount of expertise I had accumulated. As I said, I wasn’t particularly gifted in this sense, but at least I had the availability and was willing to try my best. I know that learning to operate a new device can be a daunting task but I actually wanted to invest in a life-long journey that would allow me to observe the sky as best as possible.

Since I was a beginner and knew little to nothing about telescopes, in general, I decided to get a refractor. An 80mm aperture seemed to do, especially as I didn’t have the budget for anything more. Even after all this time, it appears to me that the aperture is the feature that governs the end price of the product. Of course, other functionalities such as built-in GPS and the type of mount also have a say in the matter, although I hardly think they are as or more expensive as the optical components.

In the end, what you need to find out is your purpose. Decide on the celestial objects you want to observe and figure out your expertise. Invest some time in researching the model you want to spend your precious cents on.

 

 

Last year or sometime in the past when I was delving into the wonders of the amazing and eternally surprising Internet, I found out that there now were worms that were capable of consuming plastic as fuel. Of course, one of the first questions that passed through my mind was what came out of these worms once their digestion process was wrapped up. I didn’t want to imagine them pooping plastic if you know what I mean.

The fact is that what they do create is entirely organic and can even be used as compost if that’s what you feel like doing. The experiment took place the University of Cambridge, where Federica Bertocchini, a biologist with the Institute of Biomedicine and Biotechnology of Cantabria, Spain, got together with two of her colleagues, Christopher Howe and Paolo Bombelli.

 

The test was rather simple. They would place this outstanding species with several styrofoam cups and bits of plastic in a container and wait for something to happen. Believe it or not, one hundred worms managed to eat about 92 milligrams of plastic in as little as twelve hours. I would call that revolutionary if it weren’t for the services of one hundred worms, which seems a bit too much. Besides, 92 milligrams of plastic is about the size of 4 rice grains, so it’s not really all that impressive. However, given the fact that there’s a high chance that we will end up buried in plastic in the future centuries, it’s still a breathtaking discovery. Who knows what other critters could be capable of doing the same?

It’s also worth noting that the scientists who have performed the experiment have yet to find out exactly how the magic happened. They don’t know whether the worms consumed the plastic just because they wanted to or had developed a certain taste for it beforehand or because there were bacteria in their gut to help them digest it. Some say that it might be both.

The wonderful thing about all of this is that Bertocchini is a beekeeping enthusiast and it ever so happened that she came across several worms that ate the wax produced by the bees. Because she had little to no knowledge about the species or the reason she had found the worms consuming the wax, she kept them in a plastic bag until further notice. That’s how she discovered that the plastic bag also became food for the worms. If that’s not spectacular, I really don’t know what is.

There’s talk of an enzyme or a molecule that might be responsible for the reaction. If that’s the case, maybe scientists could transfer it to other worm species that could finally help us reduce plastic.
