  • How to get quality binoculars

    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.      

  • Why you should consider studying physics

        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.        

  • What are stereomicroscopes used for?

        I’ve always been passionate about tiny things, in that I want to find out everything that can’t be seen with the naked eye. I used to love biology classes when I was in school, and that’s because every time, I was able to learn something different and interesting. When I got married and had kids, I started focusing on the methods that I could utilize to pique my children’s interested in science. There were two ways I could do this, in my opinion. One of them was to get a good-quality telescope with the help of which my kids would be able to look at the stars every evening in the backyard or from a field nearby so that the sky wouldn’t be as polluted. The second method would be to get them a microscope. My little girl developed a passion for making her own jewelry, and Jeremy, my son, was always into repairing things. My imagination went wild with all the possibilities they had and the many career options they would have when they would grow up. Jeremy was likely to become an engineer, and the irony of it all is that is precisely what happened. While they did well in school, the fact is that they never became really interested in biology. So, when it was time for me to get them a microscope, I had to decide on a compound or a stereo one. In terms of magnification and power, a compound would have been a logical choice. However, since they didn’t really like looking at slides and preparing them on their own, it seemed to be impractical, to say the least. That is why I ended up reading a lot about stereo microscopes. This variant is designed in such a way so that to allow the user to look at larger things than slides, smears, and types of such specimens. Because they have a working distance and somewhat more room at the bottom, users can look at things like watch components, small jewelry pieces, leaves and insects, as well as a variety of other items. They’re usually made out of the same high-quality optics and other components as their compound counterparts, which is why they aren’t as affordable as some compact USB magnifiers. My research entailed going through countless reviews and forums where parents just like me expressed their opinions. So, if you’re trying to tell whether a dissecting microscope is a good idea for you, the first thing you should do is read more on this subject. For purposes like jewelry making, soldering, any type of work on electrical components and various other activities, a stereomicroscope is the perfect choice. For biological purposes, a compound is better.
