In physics, the Lorentz transformations are a six-parameter family of linear transformations from a coordinate frame in spacetime to another frame that moves at a constant velocity relative to the former. The respective inverse transformation is then parameterized by the negative of this velocity. The transformations are named after the Dutch physicist Hendrik Lorentz.
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 treatment, the theory is presented as being based on just two postulates:
- The laws of physics are invariant (identical) in all inertial frames of reference.
- The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer.
In physics, spacetime is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive where and when events occur.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them, or a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity.
A heptathlon is a track and field combined events contest made up of seven events. The name derives from the Greek επτά and ἄθλος. A competitor in a heptathlon is referred to as a heptathlete.
WrestleMania is a professional wrestling event held annually between mid-March and mid-April by the American company WWE, the world's largest professional wrestling promotion. Since premiering in 1985, 40 events have been held, with its most recent 40th edition occurring at Lincoln Financial Field in Philadelphia, Pennsylvania on April 6 and 7, 2024. WrestleMania was WWE's first-ever pay-per-view (PPV) produced and is the most successful and longest-running professional wrestling event in history. The event has been broadcast through traditional PPV since 1985 and has been available via livestreaming since WrestleMania XXX in 2014, which was WWE's first major event available through this medium. WrestleMania was conceptualized by former WWE executive chairman Vince McMahon and named by ring announcer and WWE Hall of Famer Howard Finkel. It is the company's flagship event and along with Royal Rumble, SummerSlam, Survivor Series, and Money in the Bank, it is referred to as one of the "Big Five", WWE's five biggest annual events of the year.

The Provident Credit Union Event Center, formerly and more commonly known as the Event Center Arena, is a complex consisting of an indoor arena and a fitness club on the main campus of San José State University in downtown San Jose, California. The Event Center was built in 1989 for the purpose of supporting and providing entertainment as well as recreational opportunities for the student body and university community. The facility is home to the San Jose State Spartans men's and women's basketball teams, which both compete in the Mountain West Conference.
Ariake Coliseum is an indoor sporting arena in Ariake Tennis Forest Park located in Ariake, Kōtō, Tokyo, Japan. It has a capacity of 10,000 and is one of the few professional tennis venues which has a retractable roof.
A world record is usually the best global and most important performance that is ever recorded and officially verified in a specific skill, sport, or other kind of activity. The book Guinness World Records and other world records organizations collates and publishes notable records of many. One of them is the Official World Record (O.W.R) that is the unique world records register organization recognized by the Council of the Notariats of the European Union.
Louisville Motor Speedway was a 3/8-mile race track located in Louisville, Kentucky. It was opened in 1988.
The Monte-Carlo Masters is an annual tennis tournament for male professional players held in Roquebrune-Cap-Martin, France, which borders on Monaco. It is played on clay courts at the Monte Carlo Country Club and is held in April. The tournament is part of the nine ATP Tour Masters 1000 events on the ATP Tour. Rafael Nadal has won the men's singles title a record eleven times.
In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event. It can also be used for the number of events in other types of intervals than time, and in dimension greater than 1.
A total solar eclipse will occur on Wednesday, March 30, 2033. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
An annular solar eclipse will occur on October 2, 2024. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.
A partial solar eclipse will occur on Saturday, March 29, 2025. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
UFC Fight Night: Edgar vs. Swanson was a mixed martial arts event held at the Frank Erwin Center in Austin, Texas, on November 22, 2014.
The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary(K–T)extinction, was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. Most other tetrapods weighing more than 25 kilograms also became extinct, with the exception of some ectothermic species such as sea turtles and crocodilians. It marked the end of the Cretaceous period, and with it the Mesozoic era, while heralding the beginning of the current era, the Cenozoic. In the geologic record, the K–Pg event is marked by a thin layer of sediment called the K–Pg boundary or K–T boundary, which can be found throughout the world in marine and terrestrial rocks. The boundary clay shows unusually high levels of the metal iridium, which is more common in asteroids than in the Earth's crust.
Soweto Cricket Oval is a multi-purpose stadium in Soweto, Gauteng. The ground is mainly used for organizing matches of cricket, although it has also been used occasionally for football and local events. The stadium hosted its only first-class match on October 27, 1995, where South Africa and England played to a draw. It has also hosted two List A matches, and was used as one of the venues during the 1998 Under-19 World Cup.
