What is matrix

Video and words by Jocelyn Evans , ITV News' Here's The Story Since Andrew Tate was arrested at the end of December, his Twitter account has shared at least 14 references to The Matrix. One of those is a retweet of Elon Musk, another a reply to social media star Logan Paul. So what is The Matrix and why do these three, and many others, keep talking about it? The simple answer is, it's a 1999 sci-fi film by creators Lilly and and Lana Wachowski about a simulated reality (called The Matrix) controlled by machines to trap humans. The film was, and remains, a huge hit - with people jumping on the allegory to show how it's a critique of capitalism, our current systems, and all other manner of inequality. Why's a 1999 film resurfacing now? Following his arrest in Romania on December 29, the account of influencer Andrew Tate shared this tweet: "The Matrix sent their agents". The account has continued to share unsubstantiated claims about "The Matrix" - from Tate being the victim of an attack, to encouraging others to "escape" it. A self-proclaimed misogynist, Tate's rise to fame has been rapid over the past year and his downfall dramatic. The 36-year-old has been charged with being part of an organised crime group, human trafficking and rape. Andrew Tate's not, however, the only social media giant to cite The Matrix. YouTuber Logan Paul tweeted on January 10: "the matrix is real. pray you never become its target [sic]". While Twitter's owner, Elon Musk, shared a meme of a charact...

It has been 22 years since The Matrix popularised the idea that reality is an illusion and that we are all actually lying in pods of fluid, serving as nutrients for machines. It sounds fantastical to most people – typical science fiction – but there are certain scientists and philosophers who believe that The Matrix, along with the long-awaited sequel The Matrix Resurrections, raises some serious questions of whether we really are living in a computer simulation. It’s a theory that is yet to be proved, but it hasn’t been disproved either. One of Virk’s big arguments is based on physicist John Wheeler’s phrase ‘it from bit’, the idea that the basis of the Universe is not energy or matter but information, with each subatomic particle representing a bit. “We can basically 3D print any object, and genes are just data,” says Virk. This feeds into his larger argument that if the multiverse – the hypothesis that every time a decision is made, it creates a new timeline – is real, it backs up the premise that reality is digital rather than physical. “There’s nothing in nature that duplicates an entire large physical object, particularly in an instant,” he says, “but it is pretty easy to duplicate information and then render that information as needed.” He also cites the observer effect, a phenomenon in physics in which the mere act of watching something can change it. “That doesn’t make sense if you live in a single physical reality,” says Virk, “but in video games we only render t...

1 2 3 4 The symbol for determinant is two vertical lines either side like this: |B| = 1×4 − 2×3 = 4 − 6 = −2 (Note: it is the same symbol as What is it for? The determinant helps us find the Calculating the Determinant First of all the matrix must be square (i.e. have the same number of rows as columns). Then it is just arithmetic. For a 2×2 Matrix For a 2×2 matrix (2 rows and 2 columns): a b c d e f g h i The determinant is: |A| = a(ei − fh) − b(di − fg) + c(dh − eg) "The determinant of A equals ... etc" It may look complicated, but there is a pattern: To work out the determinant of a 3×3 matrix: • Multiply a by the determinant of the 2×2 matrix that is not in a's row or column. • Likewise for b, and for c • Sum them up, but remember the minus in front of the b As a formula (remember the vertical bars || mean "determinant of"): "The determinant of A equals a times the determinant of ... etc" = −306 For 4×4 Matrices and Higher The pattern continues for 4×4 matrices: • plus a times the determinant of the matrix that is not in a's row or column, • minus b times the determinant of the matrix that is not in b's row or column, • plus c times the determinant of the matrix that is not in c's row or column, • minus d times the determinant of the matrix that is not in d's row or column, As a formula: Notice the +−+− pattern ( +a... −b... +c... −d...). This is important to remember. The pattern continues for 5×5 matrices and higher. Usually best to use a Not The Only Way This method...

Augmented Matrix An augmented matrix is a matrix formed by combining the columns of two matrices to form a new matrix. The augmented matrix is an important tool in matrices used to solve simple linear equations. The number of rows in the augmented matrix is equal to the number of variables in the linear equation. In this article, let us discuss the concept of an augmented matrix and its properties. We will learn how to solve augmented matrix and how it helps to solve a system of linear equations. Let us learn more about how to solve the augmented matrix, the properties of the augmented matrix, with the help of examples. 1. 2. 3. 4. 5. 6. What Is An Augmented Matrix? An augmented matrix is a means to solve simple linear equations. The coefficients and constant values of the linear equations are represented as a matrix, referred to as an augmented matrix. In simple terms, the augmented matrix is the combination of two simple matrices along the columns. If there are m columns in the first matrix and n columns in the second matrix, then there would be m + n columns in the augmented matrix. Let us understand the concept of augmented matrix, with the help of three linear equations, represented as follows. a 1x + b 1y + c 1z = d 1 a 2x + b 2y + c 2z = d 2 a 3x + b 3y + c 3z = d 3 The three above equations can be represented in matrix form with the coefficients as one matrix, the constant terms as another matrix, and the variables as a separate matrix. Matrix of Coefficients - A =...

Our National Aversion to Reality In an era when the president’s lawyer can go on TV and splutter, “Truth isn’t truth!” as if it’s something everyone should know, The Matrix is omnipresent. It’s not that the film was prescient. It didn’t anticipate our world. But it anticipated — and probably created — a new way of viewing that world. Since 1999, the real world has provided ample opportunity for people to turn The Matrix into the foundational text of a frighteningly thorough and self-adoring denial of whatever was in front of their noses, which roughly translates as, Reality is fake and I don’t have to listen to anyone about anything (plus maybe I know karate despite never having studied it). The Matrix concocted the perfect one-size-fits-all combination of flattery, paranoia, anti-corporate wokeness, libertarian belief in the primacy of the individual, and ideologically nonspecific anger at the system: a “Wake up, sheeple!” for its era and, even more, for ours. We live, today, in the anti-reality world The Matrix built. Read more by Mark Harris here . 2. Red Pills, the Involuntarily Celibate Villains of the 21st Century Misogyny, anti-feminism, and crude “pickup artist” dating advice have existed on the internet for a long time, but it’s the religious sensibility of The Matrix as translated into “the red pill” t...

The examples use integers (whole numbers) because the math is less complicated so it makes it easier to explain without getting lost in more difficult calculations. Yes, you can have decimals or fractions in a matrix. When you find the inverse of a matrix, you almost always have fractions (or decimals) in the resulting matrix. 1:21 he misspelled "columns" carelessly omitting the "n". Sal makes mistakes just like you or I do. None of us are perfect, even Sal. But at Khan Academy, we can keep trying to get closer to perfect. My careless math mistakes dropped substantially when I was forced to get 10 questions in a row correct to be proficient in a skill at Khan Academy. Yes, and in some fields of mathematics, they are used often. Linear equations can be expressed as matrices: 4x + 2y = 3 2x -- y = 4 would be the matrix equation | 4 2 | * | x | = | 3 | | 2 -1 | | y | | 4 | (I hope the formatting turns out on this. I'm a novice to commenting and am not sure how to display a matrix in-thread. If not, it's a 2x2 of 4, 2, 2, -1 times a 2x1 of x, y set equal to a 2x2 of 3, 4.) Luis, You can use pi (π) in a matrix. In the first matrix in this video, Sal used π as the value in the second row, first column. You can also use decimals such as 3.14. 3.14 is only an approximate value of π so if you used 3.14 when π was the exact value, you would be using a approximate value and not the exact value. I hope that helps. What I want to do in this video is explore the notion of a matrix outsi...
