User interfaces are often based on static presentations, a model ill-suited for conveying change. Consequently, events on the screen frequently startle and confuse users.

Animation can be a very effective mechanism to convey information in visualization and user interface settings. However, integrating animated presentations into user interfaces has typically been a difficult task since, to date, there has been little or no explicit support for animation in window systems or user interface toolkits. This paper describes how the Artkit user interface toolkit has been extended with new animation support abstractions designed to overcome this problem.

The Brains, Behavior and Design toolkit draws from academic research in behavioral economics and cognitive psychology to help designers and business leaders understand and influence consumer decisions.

We believe that better products, services and outcomes result from a richer understanding of the people they serve.

The toolkit is designed to be both informative and actionable - helping you integrate the latest research in human behavior and decision making into your practice.

Nautilus is a different kind of science magazine. We deliver big-picture science by reporting on a single monthly topic from multiple perspectives. Read a new chapter in the story every Thursday.

Jeff Johnson provides you with just enough background in perceptual and cognitive psychology that user interface (UI) design guidelines make intuitive sense rather than being just a list or rules to follow.

It's a new Chrome Experiment called 100,000 Stars that visualizes the stellar neighborhood. Using your mouse or trackpad, you can zoom in and out to explore our galaxy. Zooming in reveals the names of the most prominent stars close to our sun – click each name to learn more about it and see a digital rendition.

T&P — это проект, объединяющий людей, которые ищут новые знания и готовы делиться ими. Мир стремительно развивается, информация слишком быстро устаревает, и нужны новые подходы к системе образования. В этих условиях самопроизвольно возник удобный формат передачи знаний.

На веб-странице достаточно часто возникает задача визуально отделить одну информацию от другой, например, выделить текстовый блок и акцентировать на нем внимание. Подобный вопрос возникал еще до эпохи Интернета и нашел свое отражение в трудах по гештальт-психологии. Применяя подобный опыт в дизайне веб-страниц, можно быть уверенным, что мы действуем с учетом человеческого восприятия, что подтверждается трудами классиков, опытом и экспериментами.

Project AVoCet aims to provide a global database of well-documented, downloadable bird sounds in aid of environmental and ornithological research, conservation, education, and the identification and appreciation of birds and their habitats. The scientific use of avian sound recordings has long presented special challenges for a variety of reasons, including the separation of the recording and the individual responsible for the sound; the frequent lack of information provided on how a given identification was arrived at; the variability and complexity of many bird sounds; and the fact that many species are still little known and difficult to find. To help address these problems, among our major goals is the promotion of best practices in documentation so that individual recordings can serve as baseline data and can facilitate independent verification.

«Сеанс» — черно-белый журнал для умников, толстяк (320 полос) и тугодум (выходит несколько раз в год).
В его биографии было несколько очевидно-невероятных фактов.
Во-первых, он был создан еще при советской власти (80-е годы).
Во-вторых, он выжил в эпоху первоначального накопления капитала.
В-третьих, он продолжает выходить в нынешнее нулевое время (2000-е годы).
Главная задача: думать о своем времени, стараться его понять и описывать по мере сил и возможностей. Задача не менее главная: не поддаваться его соблазнам и не оправдываться его катаклизмами, свинцовыми мерзостями etс.
Главная незадача: продолжаем жить в режиме «на грани катастрофы», каждый номер делаем как последний.
Главное везение: сюда приходили, и — что важнее всего, — продолжают приходить люди талантливые. Совсем главное везение: за редчайшими исключениями, они отсюда не уходят.

Питер Морвилль выкатил расширенную версию древней триады „Context-Content-Users“, на которой строилась почти вся ИА и инфопроектирование после выхода в 1998-м году первой книги „с белым медведем“ („Information Architecture For WWW“). Два года назад, выпустив вторую редакцию „IA For WWW“, Морвилль с Розенфельдом оставили эту концепцию баланса между целями бизнеса/клиента, пользователя/посетителя и разработчика/автора без изменений.

Some cells are visible to the unaided eye
The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny.

Smaller cells are easily visible under a light microscope. It’s even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. Light microscopes use a system of lenses to magnify an image. The power of a light microscope is limited by the wavelength of visible light, which is about 500 nm. The most powerful light microscopes can resolve bacteria but not viruses.

Welcome to the Earth Impact Effects Program: an easy-to-use, interactive web site for estimating the regional environmental consequences of an impact on Earth. This program will estimate the ejecta distribution, ground shaking, atmospheric blast wave, and thermal effects of an impact as well as the size of the crater produced.

Peer reviewed scientific journal on the Internet

The Internet has become impossible to ignore in the past two years. Even people who do not own a computer and have no opportunity to "surf the net" could not have missed the news stories about the Internet, many of which speculate about its effects on the ever-increasing number of people who are on line. Why, then, have communications researchers, historically concerned with exploring the effects of mass media, nearly ignored the Internet? With 25 million people estimated to be communicating on the Internet, should communication researchers now consider this network of networks [1] a mass medium? Until recently, mass communications researchers have overlooked not only the Internet but the entire field of computer-mediated communication, staying instead with the traditional forms of broadcast and print media that fit much more conveniently into models for appropriate research topics and theories of mass communication.

This isn’t a complicated vocabulary, with thousands of words. Nonetheless, it’s clear that for many animals, alarm calls are more than simple squawks of fear. Vervet monkeys, for instance, use different sounds to warn of different types of predator. “Leopard!” is not the same as “snake!” or “eagle!” If you hide a loudspeaker in the bushes, and startle unsuspecting monkeys by playing recordings of “snake!” at them, they will look around at the ground. “Eagle!” makes them look up. “Leopard!” sends them scampering to the trees.

SCIgen is a program that generates random Computer Science research papers, including graphs, figures, and citations. It uses a hand-written context-free grammar to form all elements of the papers. Our aim here is to maximize amusement, rather than coherence.
