As sure as death and taxes, sitting at a wobbly table at one time or another is inescapable. With your weight on it, the table shifts from one end to the other, lifting one leg in the air and then the other; a parade of seesaws, especially if you have someone sitting on the other end.
Say goodbye to the age of metal robots—C-3PO and K9 are a thing of the (future) past! Anette Hosoi, Professor of Mechanical Engineering and Applied Mathematics at MIT, and her former graduate student Nadia Cheng, have created a robotic material closely resembling human skin.
2 + 2 = 4. That's about as much math as I can handle without a calculator on a daily basis. I literally hate doing math more than anything in life, mostly because I'm not good at it—and I hate doing things I'm not good at.
Imagine wearing your HoloLens, then reaching out to touch a hologram and actually feeling it. Mind blown, right?! Now imagine that same hologram responding to your touch. I don't mean in the way holograms currently respond to an air tap, but a much more refined and precise touch. Maybe you touch a character on the shoulder and it turns around to see you, or maybe you hit a button in the air and it reacts accordingly.
Welcome back, my rookie hackers! As hackers, we are often faced with the hurdle of cryptography and encryption. In some cases, we use it to hide our actions and messages. Many applications and protocols use encryption to maintain confidentiality and integrity of data. To be able to crack passwords and encrypted protocols such as SSL and wireless, you need to at least be familiar with the concepts and terminology of cryptography and encryption.
Not that long ago I wrote an article discussing what it would be like, realistically, if you were to accidentally travel back in time to the Victorian era. At the end of that article, I mentioned that the best thing you could bring with you on a time-traveling adventure is a Kindle, or similar e-reader, stuffed full of the knowledge of the 21st century. Why a Kindle? Well, I own a Kindle, and I love it. However, there's far more to it than that.
Merge VR, a company mostly known for its virtual reality experiences, is moving into and creating an augmented reality experience that combines an iPhone or Android smartphone, a set of goggles to put your phone in, and a box about the size of a Rubik's Cube which looks more akin to the Lament Configuration seen in the Hellraiser film series. When used in concert with the smartphone and goggles, the toy cube, called Holo Cube, becomes one of many AR experiences.
Robots are always really cool, if you ask me. Sometimes they're made out of Legos, and that's even cooler.
Hello again, and welcome back to another tutorial on functions, this time, covering recursion. What Is Recursion?
Becoming a competitive candidate in IT and Data Science takes more than knowing a few coding languages and being good with computers. To really stand out from the crowd, your knowledge should be extensive and your experience should be diverse. The 2021 Complete Computer Science Training Bundle provides that depth of knowledge and a starting point for gathering that experience. Right now, it's on sale for just $39.99.
Java is one of the world's leading programming languages thanks to its virtually endless array of applications. Since Java's initial release in 1998, this Open Source platform has become beloved by coders for its speed, flexibility, and dependability.
A gold-medal winning entry into the iGEM synthetic biology competition could change the way we look at Esherichia coli, the bacteria better known as E. coli.
Hello again, reader! In this post, we are going to cover some data types and how to declare variables. It shouldn't be too hard so just sit back, relax, grab some popcorn and enjoy the ride (while you still can!).
Welcome back, my novice hackers! In a recent tutorial, I showed you how to use shikata_ga_nai to change the signature of a payload to evade detection by security devices (firewalls, IDS, etc.) and AV software.
IT is a competitive field, and finding success requires more than knowledge of a couple of coding languages or knowing how to google really well. To stand out among your peers and competitors, you should learn everything you can and get as much diverse experience as is available.
If you've already read the first part exploring what geniuses actually eat as opposed to what the rest of us are told to eat for brain health, you've noticed that there are some big discrepancies. Instead of favoring healthy, wholesome foods high in antioxidants, lots of high-achieving types tend to go for caffeine, sugar, and processed foods. One notable health habit practiced by many: eating breakfast.
OSAGYEFO DR. KWAME NKRUMAH (1909-72) Founder and Father of the Nation Osagyefo Dr. Kwame Nkrumah, the first Prime Minister and President of Ghana, stands out not only among the Big Six but also among the greatest statesmen of history. It was he who canalized the discontent of the people of the Gold Coast Colony into the highly organized movement of protest against British rule, and within a relatively short period won political independence for Ghana on March 6, 1957. With Ghana independent, ...
The world of investment and finance can be labyrinthine in its very nature — and even more complicated in regards to augmented and mixed reality. While these new emergent technologies are teeming with explosive levels of unrealized potential, there's still a big layer of uncertainty in terms of return — but these investors aren't afraid to take the leap.
I am an English major physically allergic to all algebraic formulas, so you're unlikely to get any help from me when it comes to solving any expressions. But in the glorious technological age we live in, there are plenty of apps that actually make math and problem solving fun, even a little bit addictive.
One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...
One could argue that, at least for the moment, software development is more important to the augmented reality experience than hardware. Since a viable augmented reality headset has yet to emerge for the broader, mainstream consumer market, currently, the same devices that make texting and selfies possible are leading the charge to enable easy-to-use AR experiences.
The Calculator app is probably one of Apple's most-used iPhone apps, yet I always meet people who don't know all the little tricks there are to using it more efficiently. You may know most of them, but there's a chance you don't or at least forget about some of them.
In this video tutorial, viewers learn how to calculate the standard deviation of a data set. The standard deviation of a statistical population, a data set, or a probability distribution is the square root of its variance. To calculate the standard deviation, users will need to follow these steps. 1) Find the mean of the data. 2) Subtract the mean from each data point. 3) Square each of the values you got in step 2. 4) Then find the mean of the values you get from step 3. 5) Finally, square r...
This is an introductory educational video that shows how to find the area of a triangle with decimal measurements.
In this video tutorial, viewers learn how to solve for the circumference and area of a circle. The circumference is the distance around a closed curve. The formula for circumference is C= pi x d. The diameter is two times the radius (d= 2r or r= d/2). The value of pi is approximately 3.14. The formula for the area of a circle is A= Pi x r^2. This video provides examples and demonstrations on how to use and solve with both the formulas. This video will benefit those viewers who are struggling ...
In this video tutorial, viewers learn how to solve the area of a triangle. The formula for the area of a triangle is A = ½ x b x h or bh/2. The base of the triangle is always at the bottom; it is the side that the triangle sits on. The height is the length between the base and the highest point of the triangle. Multiply the base and height of a triangle; then divide by two or multiply by half. The measurement unit of the answer should be squared. This video will benefit those viewers who need...
In my opinion, Isaac Newton is definitely the number two astronomer, right below Galileo Galilei. His discoveries were very important to uncovering the secrets of space, and he deserves to be remembered.
I'm starting a series on the top astronomers, with probably about eleven astronomers that I will be covering overall. So, let's start out from the top, with the top most important astronomer. In my opinion, Galileo Galilei is the top astronomer.
WonderHowTo is made up niche communities called Worlds. If you've yet to join one (or create your own), get a taste below of what's going on in the community. Check in every Wednesday for a roundup of new activities and projects.
Tom Friedman is one of my favorite artists. He's got a great sense of humor, and his work is meticulous and beautiful. He forays into Math Art, and from a partisan perspective, he seems to be inspired by mathematics, but the end results are more of a whimsical twist than a mathematically "correct" execution. But I could be totally wrong. Comment below and fill me in.
Here at WonderHowTo we're overflowing with top-notch origami tutorials. However, when it comes to the lesser known art of kirigami, we could always use a couple more enthusiasts. Kirigami is a form of origami that (unlike origami) involves making intricate cuts, and the results are often incredible.
It was brought up a while back in a Community Call to Arms that *math* is handy for encryption (and let's face it, everything) so let us go over things you just have to know. "In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values."[source]
Can you dissect an equilateral triangle into pieces that can be rearranged into a square? If you think you can, you may have mastered the Pythagorean theorem.
It's gigantic! It can handle over 100 simultaneous touch points! It has a curvature of 135 degrees! And best of all, it is not the newest, insanely expensive gadget to hit the market. Instead, this touchscreen was hacked together with a bunch of PCs, video cameras, projectors and cheap infrared illuminators at the University of Groningen, in the Netherlands. It works like this: "The cameras, illuminators and projectors are all placed behind a large, cylindrical screen (formally used as a 3D t...
This is pretty awesome, check it out! Wolfram Alpha's Facebook Report Analyzes Every Dark Corner of Your Facebook Activity.
Could the world really be coming to an end tomorrow? Presuming you believe the biblical prediction from 89-year-old Harold Camping, May 21st, 2011 is undeniably Judgment Day. If you have confidence in that prophecy, you're probably not even reading this because you're too busy either A) preparing for the Rapture or B) sitting in your backyard bunker hoping to outwit annihilationism.
Without Richard Channing Garfield the world would be a much grayer and less interesting place today, at least for all of us. He created Magic in college, playtested it throughout, accidentally found a publisher for it, and wound up the the most well-known and successful paper game designer in the world (sorry Guygax, make something new why don't ya?). He does not seek the limelight, has not had a snappy biography written about him (or his game, amazingly enough) and I thought we should pay a ...
In the dojo, what ISN’T said is often as important as what IS said. To most of us who’ve been raised in the USA, the reticence we encounter in the dojo can be off-putting. American society is very “content” oriented. Our legal contracts, for instance, run for pages and pages. Everything needs to be spelled out. In “context-oriented” societies there is far less reliance on such a literal approach. Much more importance is placed on the relationship between the two parties entering into an agree...
Another week has passed on the online battlefield as the CISPA legislation continues to grind away at our freedom. Here at Null Byte, we try to keep our community informed and knowledgeable at the same time—and that means creating content for them to learn from.
