  • What is a senior walker and who might need one?

      As much as we would love to stay young forever, our bodies have the nasty tendency of not listening to our hearts after a while. Obviously, a healthy lifestyle combined with active workout routines and a balanced diet can lead to a strong and fulfilling life even after 65-70 years. Unfortunately, even after that age our bodies slowly start to shut down and we start experiencing plenty of health issues, including reduced mobility, and joint pains. For those who deal with reality’s wake up call but still want to be as independent as possible, senior walkers seem like the perfect solution. Here is everything you should know about them and how to properly use them to increase your mobility.

    Who needs a walker?

    Contrary to the common opinion, walkers are not only intended for old people. On the contrary, anyone who experiences joint or bone pains, back pains or who has suffered minor or major surgeries might require a walker at a certain point. In fact, they are quite common devices that can help people recover after surgeries and physical procedures faster, regardless of their age. Professional athletes will often choose walkers days after surgeries and might keep on using them for months until they achieve full recovery.  

    How many types of walkers are there?

    Depending on your age and type of injury you suffer, your physical therapist or doctor might suggest a certain type of walker for you. Generally speaking, the most common types are the standard walker, the two-wheel one, the three-wheel one, and the knee walker. All of these devices are suitable for seniors, depending on their mobility and how much they can walk without getting tired. The standard products feature four non-skid legs with rubber tips to provide more stability. They are mainly used by people who just got out of surgery or by seniors who require improved stability and don’t hurry too much. On the opposite corner, the four-wheel walker was particularly designed for those who don’t need balance or stability but rather a faster way to move around. They often resemble smaller wheelchairs and even come with a small depositing area where you can put your groceries or bag.  

    How much should they weigh?

    If you plan on buying this type of product you should also consider its weight. Obviously, standard walkers are heavier as they need to be reliable and offer you the security you need. In addition, since they don’t feature wheels, they are also more difficult to transport and occupy more space. On the other side, wheeled walkers are lighter and portable and, thanks to their foldable design, you can easily carry them with you everywhere you go.  

  • 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.      

  • Nikon point and shoot cameras – cool picks

    With almost 100 hundred years of experience in the field of optics and imaging technology, we can’t expect from Nikon but to amaze us further. While small brands can feel the cold wind of smartphone technology rising, a titan such as Nikon doesn’t seem to have anything to worry about. In 2017, many have turned their attention to what has been called the “Nikon beast”, the Coolpix P900, a bridge camera belonging to the wider Coolpix series of compact cameras designed to accompany the photographer in a wide variety of situations and decors. The P900 introduces an equivalent focal length of 24-2000 mm, with 4000mm Dynamic Fine Zoom, and that, my friends, means an 83x zoom, which is enough to take a close look at the spots on the Moon or the feathers of your favorite bird. Packed with an LCD display with 921k dot-resolution, the P900 offers an electronic viewfinder, it can go from 7 fps to 120 fps, and you can transfer your work via the built-in Wi-Fi and NFC technology. The only drawback of this model, according to users and testers around the world is its bulkiness, that distances it a little from the classic compact camera design.   Another Nikon breakthrough this year comes in the form of the Coolpix A900, a new arrival in the A series. The Coolpix A900. The first feature that stands out on this compact camera is how small and compact it really is, competing with any regular-sized smartphone. 4K video capture at 30fps give you the perfect tool to create beautiful photography. A 921k-dot resolution LCD screen that tilts over gives you the possibility to integrate yourself in the scenery, and all these wonderful features are topped with Wi-Fi, NFC and Blueooth connectivity. Lastly, the Coolpix B700 comes with a 60x optical zoom with an equivalent 24-1440mm focal length, seconded by 120x Dynamic Fine Zoom, using a super telephoto Nikkor Ed glass lens. A 3’’ tilting LCD display, 4k video capture at 30fps, raw image capture and ISO 100-1600 (expandable to ISO 3200), this model is nothing but power. With the same connectivity features as its abovementioned “siblings”, the B700 is a great investment for anyone who want to rise above entry-level in creative photography.

  • Amazing online resources for studying anything

      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.

    MIT OpenCourseware

    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.

    iTunes free courses

    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.  

    GED for free

    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.  

  • 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 stereo microscopes 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.
