I believe we all have a purpose on this Earth and we all struggle to acquire as much as possible in this life, and hopefully leaving something meaningful behind for further generations. And, with the free access to unlimited resources on the Internet, it comes as no surprise that more and more people choose to quit their former jobs and trying to pick up new skills, change their lives, and approach new career possibilities. The free world we are all experiencing today also puts great responsibility on our shoulders, trying to make us more responsible for our actions. And the number one rule in becoming a true adult is to disseminate the information and filter it through your own rationality. Luckily for all of us, learning new skills and even taking new classes to improve our minds and lives has never been easier. There are countless online resources that offer free access to dozens of online classes for everyone around the world. Let’s take a look at some of the biggest free online databases.The valuable Institute of Technology from Massachusetts offers free access to hundreds of online courses in various departments. Some of the courses are suitable for students across the world while some others refer to improving a certain set of skills. From cooking classes to learn about molecular biology, all of these classes can now be learned online courtesy of MIT. Without any registration required, you’ll have access to lecture notes, videos, exams, and others. Some of the most popular classes include psychology, microeconomics, calculus, engineering dynamics, biology, and electrical engineering. In addition, some of the courses are also translated into different languages so you can learn everything in your own mother tongue. Free education has never been easier for members of the Apple community. Thanks to a simple app coordinated from iTunes, Apple puts at the disposal of its users hundreds of online free classes you can join. However, the catch is that you can only access the courses from an Apple platform - iPhone, iPad, Mac OS computers, and others. As you would have probably guessed, the platform is not compatible with Google, Android or Windows mobile devices so you’ll only have access to the classes you’re interested in as long as you’re logged in with your iTunes account from an Apple-supported platform. On the bright side, you can access free courses on various topics, and learn them in your own language. This is a great online platform that helps people all over the country learn to get their GED exam and complete school classes. The platform is both suitable for students who didn’t finish high school or for people who want to take up classes again to complete their studies and receive better-paid jobs. Although useful, you may want to use this free resource with additional classes as there are no advanced courses or additional activities to help you with your studying routine.
Observing nature can teach you a lot of things. This is something I want my children to be interested in, and that is why I strive to provide them with the best means to achieve knowledge and to do so in a fun way. Kids will always be kids, and their attention span can be very short, but I believe in stimulating their intellect and curiosity, and a pair of binoculars can be helpful. Bringing everything closer makes things more interesting, and this is something that binoculars can do with ease. However, if you look around like I did, you will notice that there are plenty of models available and they can vary in pricing and features a lot. I did some research on the topic, and I discovered some things that are more important than others when it comes to choosing good quality binoculars. Understanding the difference between roof and Porro prisms The prism is an essential element and can significantly influence the way a pair of binoculars looks like. Some are chunky, and others slim and elegant. Before researching binoculars in general, I didn’t know the physical aspect was so much influenced by the type of prism used. Why is the prism necessary? To put it in simple terms, without it, the image shown through your binoculars will be upside down. The prism organizes the glass elements, and, in a roof-prism model, these elements are set in a line, which leads to a streamlined, elegant design. Porro-prism models, on the other hand, have these elements offset from one another, which makes them heavier and less streamlined. However, what you should know is that these models offer better depth of field and wider field of view. Picking the right magnification This is the type of thing where you might feel tempted to say that the higher the number, the better. However, some factors influence the overall performance of a pair of binoculars. That is why I would recommend getting an 8x magnification model, rather than a 10x magnification pair. What happens is that the larger the magnification, the more distance you can cover. However, this comes at a price. Your field of view will become narrower, and less than ideal light conditions create a darker image. Also, the factor that I find important is the stabilization. A model with higher magnification will noticeable influence image stabilization, and unless you have steady hands, the image you see through the lenses will be shaky. The eye relief factor One aspect that I think it’s often overlooked when shopping for a pair of binoculars is eye relief. This stands for the available distance between the binoculars and your eyes. A model with a higher value for eye relief lets you keep the binoculars at a comfortable distance from your eyes, without the need to press them against your face to see better.
I never was a big fan of science, in general, and I blame that on my education or rather, the lack of. I didn’t develop a keen interest in studying physics, for example, but that was partly due to the fact that my parents didn’t help me a lot with homework and my colleagues and buddies weren’t extremely gifted, either. I did manage to make some changes in my education over time, but that took a lot of time and effort. Now that I have started a family, I’m interested in giving the best to my kids. That includes education. I started teaching my kids the basics of physics, most of which I learned online or via other resources aside from school. Unfortunately, I have to be honest and admit that the teachers I had while I was in school did little to nothing when it comes to piquing our interest in this domain. Physics is useful and interesting. It can help you find out and grasps the notions that can assist you in understanding how your body works. It can tell you how cars work, or how most earthquakes and hurricanes develop. Let’s take optics, for example. If you were to look at the way light is transmitted through a set of lenses, you’d be able to study a variety of domains. Microscopes are based on optics, for instance, and you can use them for a variety of things, whether you want to look at cells and tissues or you’d like to make your own pieces of jewelry. Telescopes are also composed of optics, and you can use them to look at stars. So, here you have it, two products that seem to have nothing in common, and they are actually based on almost the same principles. Physics is challenging and requires a bit of commitment because you can’t start studying it without knowing absolutely anything. That’s why it takes time and a bit of effort to learn its basics, so it might not be the perfect domain to study for a procrastinator. I would start by reading some books written by Stephen Hawking, in my opinion. Some of these titles can let you know a lot of things without stumbling upon overly complicated information that you would risk failing to understand. Because every endeavor, be it educational or not, needs a bit of planning, I would also suggest making a studying schedule. Don’t overdo it and try to keep your expectations real. If you have a job like I do, it might be a good idea to study something new once a week for as many as two hours. I wouldn’t have more time for this, but that’s because I have kids and a family.
