This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

There has been much discussion in recent years, on this campus and elsewhere, about the death of the book. Digitization and various forms of electronic media, some critics say, are rendering the printed text as obsolete as the writing quill. In this subject, we will examine the claims for and against the demise of the book, but we will also supplement these arguments with an historical perspective they lack: we will examine texts, printing technologies, and reading communities from roughly 1450 to the present. We will begin with the theoretical and historical overviews of Walter Ong and Elizabeth Eisenstein, after which we will study specific cases such as English chapbooks, Inkan knotted and dyed strings, late nineteenth-century recording devices, and newspapers online today. We will also visit a rare book library and make a poster on a hand-set printing press.

In her final semester as a business major, Jade Trinh was uninspired by the obvious career paths open to her. In her 2011 BIF Talk, Trinh recounts her story of stumbling into an entrepreneurship course that revealed an unexpected and exciting new path. She argues that students crave the kinds of real-world, experiential learning environments she was fortunate enough to encounter and urges that experiences like hers should not be the exception, but the rule.

Gordon Moore, co-founder of Intel Corporation, to whom the term "Moore's Law" is attributed, speaks about the ubiquitous microchip. (27 minutes)

This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. The animation consists of four parts - an introduction, fuel cell components, chemical process, and fuel cell stack.

In this video segment adapted from NOVA scienceNOW, hydrogen fuel cell cars promise pollution-free driving, but will we see them anytime soon?

In this activity, students consider the impact and sustainability of use of different classes of biofuels on the economy, the environment, and society. Students also learn about bioelectricity and how converting biomass to electricity may be the more efficient way to fuel cars in the 21st century.

In this video segment adapted from FETCH!, contestants are challenged to use materials from a garbage dump to build a boat that floats, can be steered, and is propelled by something other than oars.

Just after World War II, nuclear scientists turned their attention from fission to fusion. This video segment adapted from AMERICAN EXPERIENCE looks at the beginnings of thermonuclear power generation.

This presentation is a part of the subjective assignment done for a MOOC course on Academic Writing in SWAYAM. This presentation gives a bird's eye view about how the technology is shaping the Banking industry in India and what are its advantages and limitations.

In this brief video, NASA scientists discuss the Global Precipitation Measurement (GPM) mission and its role in studying and tracking Earth's freshwater resources. The GPM mission will advance our understanding of Earth's water and energy cycles, improve the forecasting of extreme events that cause natural disasters, and extend current capabilities of using satellite precipitation information to directly benefit society.

During a scavenger hunt and an art project, students learn how to use a handheld GPS receiver for personal navigation. Teachers can request assistance from the Institute of Navigation to find nearby members with experience in using GPS and in locating receivers to use.

This video segment adapted from NOVA shows how Galileo, using his newly developed refracting telescope, observed four of Jupiter's moons, the first astronomical bodies to be discovered since ancient times.

The purpose of the course is to cultivate the sensibilities necessary for effective planning practice. This objective rests on one key assumption: that a set of key sensibilities creates the right mindset for practice.

Students learn how a telescope's aperture determines how much light it can gather in this Moveable Museum unit. It has three procedures, one of which is optional. The four-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and information about where to obtain supplies. In this activity, the light collector is not a lens or a mirror, but a hole in a cardboard box. Light enters through the hole and lights up the box. Users can change the size of the hole and see how the amount of light entering the box changes. The results show why increasing the aperture of a telescope increases the amount of light it can collect.

What can we learn about science and technology–and what can we do with that knowledge? Who are “we” in these questions?–whose knowledge and expertise gets made into public policy, new medicines, topics of cultural and political discourse, science education, and so on? How can expertise and lay knowledge about science and technology be reconciled in a democratic society? How can we make sense of the interactions of living and non-living, humans and non-humans, individual and collectivities in the production of scientific knowledge and technologies?
The course takes these questions as entry points into an ever-growing body of work to which feminist, anti-racist, and other critical analysts and activists have made significant contributions. The course also takes these questions as an invitation to practice challenging the barriers of expertise, gender, race, class, and place that restrict wider access to and understanding of the production of scientific knowledge and technologies. In that spirit, students participate in an innovative, problem-based learning (PBL) approach that allows them to shape their own directions of inquiry and develop their skills as investigators and prospective teachers. At the same time the PBL cases engage students’ critical faculties as they learn about existing analyses of gender, race, and the complexities of science and technology, guided by individualized bibliographies co-constructed with the instructors and by the projects of the other students. Students from all fields and levels of preparation are encouraged to join the course.

This course examines relationships between identity and participation in Japanese popular culture as a way of understanding the changing character of media, capitalism, fan communities, and culture. It emphasizes contemporary popular culture and theories of gender, sexuality, race, and the workings of power and value in global culture industries. Topics include manga (comic books), hip-hop and other popular music, anime and feature films, video games, contemporary literature, and online communication. Students present analyses and develop a final project based on a particular aspect of gender and popular culture.

This course considers a wide range of issues related to the contemporary and historical use of technology, the development of new technologies, and the cultural representation of technology, including the role women have played in the development of technology and the effect of technological change on the roles of women and ideas of gender. It discusses the social implications of technology and its understanding and deployment in different cultural contexts. It investigates the relationships between technology and identity categories, such as gender, race, class, and sexuality, and examines how technology offers possibilities for new social relations and how to evaluate them.
