This asteroid was visited by the NEAR Shoemaker spacecraft during June 1997, on its way to asteroid 433 Eros. The spacecraft took pictures of one side of the asteroid, finding many big craters that have gouged out depressions in the surface. It is currently the biggest asteroid to be visited by a spacecraft, and the first C-type asteroid to be so explored.
253 Mathilde is very dark. The asteroid has a number of very big craters, with the individual craters being named for coal fields and basins around the world. The two biggest craters, Ishikari (29.3 km) and Karoo (33.4 km), are as wide as the asteroid's average radius. The impacts appear to have blown big volumes off the asteroid, as suggested by the angular edges of the craters.
The density measured by NEAR Shoemaker, 1,300 kg/m³, is less than half that of a normal carbonaceous chondrite; this may indicate that the asteroid is very loosely packed rubble pile (an asteroid that has been broken apart by a collision and pulled back together by gravity). The same is true of several C-type asteroids studied by ground-based telescopes with adaptive optics systems (45 Eugenia, 90 Antiope, 87 Sylvia and 121 Hermione). Up to 50% of the volume inside of 253 Mathilde has open space. However, the existence of a 20-km-long scarp may indicate that the asteroid does have some structural strength, so it could contain some big internal components. The low interior density is an inefficient transmitter of impact shock through the asteroid, which also helps to preserve the surface features to a high degree.
Mathilde's orbit is eccentric, taking it to the farther reaches of the Main belt. Nonetheless, the orbit lies between the orbits of Mars and Jupiter; it does not cross the planetary orbits. It also has one of the slowest rotation periods of the known asteroids — most asteroids have a rotation period in the range of 2 – 24 hours. Because of the slow rotation rate, NEAR Shoemaker was only able to take pictures of 60% of the asteroid's surface. The slow rate of rotation may been accounted for by a moon orbiting the asteroid, but a search of the NEAR images revealed none bigger than 10 km in diameter out to 20 times the radius of 253 Mathilde.
Yōkai
Yōkai are creature in old Japanese stories, such as oni, kappa, or tengu. They have mysterious supernatural powers. There are thousands of yōkai. In the Edo period, yōkai were characters in story books. Recently, many new yōkai have been made. There is even a yōkai dictionary. The yōkai are monsters or ghosts in Japanese tradition. In the past people believed they caused disease, accidents, and natural disasters. People were often scared of them.
The most famous yōkai are Tengu, Oni (Japanese ogre), and Kyubi no Kitsune (a fox with nine tails). When some people and animals are filled with hate, they became yōkai. For example, Sutoku. Sutoku (Japanese ancient emperor) died filled with hate. Then, he became a Tengu and caused a disaster. Also, a cat which lived too long time became Nekomata.
Recently, yōkai are familiar with people as subculture in Japan.
In recent decades, the yōkai have been frequently depicted in Japanese fiction and media, particularly in horror or fantasy-themed works, such as in manga, anime and films, as well as in videogames, a notable example of this is the manga "GeGeGe no Kitarō", written by mangaka Shigeru Mizuki, of which is entirely based on the "yōkai" myth. Other examples includes the manga series "Death Note", "Pet Shop of Horrors", "Good Luck Girl!", light novel "Ghost Hunt", the 2011 animated film "A Letter to Momo" and RPG videogame franchise "Yo-kai Watch".

A stamp album is a book, often loose-leafed (with its papers not attached to the book, but hanging loose inside), in which a collection of postage stamps may be stored and displayed. There are also stamp albums in the form of binders.
Many collectors buy preprinted (already printed) albums and pages, which are made and sold. The usual format is to print a black-and-white picture of the stamp in each space. Album pages are almost always one-sided pages.
Stamp hinges are used by stamp collectors to put postage stamps onto the pages of the stamp album.
Stamp collector
A stamp collector or philatelist collects postage stamps as a hobby. Stamp collectors normally keep the stamps in books called stamp albums. A philatelist can study various aspects of definitive stamps and other types of stamps, cancellations, and other philatelic materials.
There are many stamp collecting clubs around the world. Belonging to a stamp club or philatelic society has many advantages. For example, Royal Philatelic Society of Canada members receive magazines, can get help with questions through phone support, and purchase insurance for their collections at a discounted group rate.
Pansexuality
Pansexual people are people attracted to people regardless of their gender. This is similar to many bisexual people. The word "pansexual" comes from the Greek word 'pan-', meaning "all".
Pansexuality is one of the many sexualities from the LGBT community. Although the sexuality overlaps with bisexuality, both labels are accepted as long as the person is comfortable and respects the other equally.
Originally, Sigmund Freud invented the word "pansexual". It meant attraction to all ages and species - pedophilia and zoophilia. The definition has changed since then.
Pansexuality is often described as ‘attraction to people regardless of gender (including those who may not identify as boys or girls or as men or women, or to those who are intersex, genderfluid, etc.) pansexuality can also be described as "gender blind".
Some may describe it as "gender blind" because those who identify as pansexual do not consider gender important when they are attracted to others.
Pansexuality is considered the opposite of asexuality, as pansexuality means a person may be sexually attracted to anyone regardless of their gender identity, but asexuality means a person is sexually attracted to no one. However, pansexuals are not necessarily sexually attracted to everyone they meet, nor do they necessarily have strong sex drives.
The pansexual colors from the pride flag all have different meanings, pink meaning women, blue, men, and yellow for people (for an example) of a non-binary gender, such as agender, bigender or genderfluid.
Adverse effect (medicine)
In medicine, an adverse effect is a harmful and undesired effect that results from a therapy like medication, chemotherapy, surgery or other intervention. An adverse effect may be called a "side-effect" (when it is less important than the therapeutic effect).
It may result from an unsuitable or incorrect dosage or procedure (which could be caused by medical error). Some adverse effects happen only at the beginning or a change of a treatment.
In many countries, adverse effects have to be reported and researched in clinical trials and included into the patient information accompanying medical devices and drugs for sale to the public.
Technosexuality
Technosexuality is a word used to mean two things:
Sometimes "technosexual" is used as an insult, implying that someone would prefer a sex toy to an actual sexual partner.
The Calvin Klein company trademarked the term "technosexual" in 2005.
'i-wear' (or 'e-wear') is "intelligent" clothing that joins fashion with technology. i-wear was born out of the collaboration between European fashion designers and computer technicians. i-wear is a step made towards technologizing a person's fashion, and in this sense, a person can be more as a part of technosexuality.
Antisexuality
Antisexualism, sex-negativity or antisexuality is opposition or hostility towards sexual behavior and sexuality.
