Students apply what they know about light polarization and attenuation (learned in the associated lesson) to design, build, test, refine and then advertise their prototypes for more effective sunglasses. Presented as a hypothetical design scenario, students act as engineers who are challenged to create improved sunglasses that reduce glare and lower light intensity while increasing eye protection from UVA and UVB radiation compared to an existing model of sunglasses—and make them as inexpensive as possible. They use a light meter to measure and compare light intensities through the commercial sunglasses and their prototype lenses. They consider the project requirements and constraints in their designs. They brainstorm and evaluate possible design ideas. They keep track of materials costs. They create and present advertisements to the class that promote the sunglasses benefits, using collected data to justify their claims. A grading rubric and reflection handout are provided.

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

This online exhibit is a visual illusion in which a fuzzy blue dot disappears into a green background. The illusion is created by the tiny jittering movements that your eyes are continually making. Take your investigation further by making your own hands-on fading dot illusion - instructions are at the Exploratorium Snack website (see related link).

This team-taught multidisciplinary course provides information relevant to the conduct and interpretation of human brain mapping studies. It begins with in-depth coverage of the physics of image formation, mechanisms of image contrast, and the physiological basis for image signals. Parenchymal and cerebrovascular neuroanatomy and application of sophisticated structural analysis algorithms for segmentation and registration of functional data are discussed. Additional topics include: fMRI experimental design including block design, event related and exploratory data analysis methods, and building and applying statistical models for fMRI data; and human subject issues including informed consent, institutional review board requirements and safety in the high field environment.

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

An old saying holds that “there are many more good ideas in the world than good ideas implemented.” This is a case based introduction to the fundamentals of effective implementation. Developed with the needs and interests of planners—but also with broad potential application—in mind, this course is a fast paced, case driven introduction to developing strategy for organizations and projects, managing operations, recruiting and developing talent, taking calculated risks, measuring results (performance), and leading adaptive change, for example where new mental models and habits are required but also challenging to promote. Our cases are set in the U.S. and the developing world and in multiple work sectors (urban redevelopment, transportation, workforce development, housing, etc.). We will draw on public, private, and nonprofit implementation concepts and experience.
This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.

Students are introduced to the Robotics Peripheral Vision Grand Challenge question. They are asked to write journal responses to the question and brainstorm what information they require to answer the question. Their ideas are shared with the class and recorded. Then, students share their ideas with each other and brainstorm any additional ideas. Next, students draw a basis for the average peripheral vision of humans and then compare that range to the range of two different focal lengths in a camera. Through the associated activity provides, students see the differences between human and computer vision.

Students learn about how ultrasonic sensors work, reinforcing the connection between this sensor and how humans, bats and dolphins estimate distance. They learn the echolocation process sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects. Two mini-activities, which use LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors, give students a chance to experiment with ultrasonic sensors in preparation for the associated activity. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, and details about the LEGO ultrasonic sensor. Pre/post quizzes are provided. This lesson and its associated activity enable students to gain a deeper understanding of how robots can take sensor input and use it to make decisions via programming.

This course analyzes seminal work directed at the development of a computational understanding of human intelligence, such as work on learning, language, vision, event representation, commonsense reasoning, self reflection, story understanding, and analogy. It reviews visionary ideas of Turing, Minsky, and other influential thinkers and examines the implications of work on brain scanning, developmental psychology, and cognitive psychology. There is an emphasis on discussion and analysis of original papers; students taking the graduate version complete additional exercises and a substantial term project.

Vision anomalies can affect a child’s performance in school, if they are severe enough. Treatment for vision anomalies depends on identification, and the best people to identify vision problems in children are often teachers, because they spend the most time with them, in an environment that requires great vision skills. Teachers often do not know the signs or symptoms of vision problems in their students however. This PowerPoint strives to educate teachers on basic vision and vision anomalies that they can detect in their students.

This course is an introduction to the mammalian nervous system, with emphasis on the structure and function of the human brain. Topics include the function of nerve cells, sensory systems, control of movement, learning and memory, and diseases of the brain.

This course provides practical instruction in the fundamentals of analog and digital SLR and medium/large format camera operation, film exposure and development, black and white darkroom techniques, digital imaging, and studio lighting.
This semester we will explore the MIT Department of Brain and Cognitive Sciences for our theme- and site-specific term project, which provides opportunities to develop technical skills and experimental photographic techniques, and for personal artistic exploration. Final projects will be presented on site in exhibition format.
Work in progress is continuously presented and discussed in a critical forum. Lectures, readings, visiting professionals, group discussions, and site visits encourage aesthetic appreciation of the medium and a deeper understanding of our semester theme, as well as a critical awareness of how images in our culture are produced and constructed.

This course is a survey of the scientific study of human nature, including how the mind works, and how the brain supports the mind. Topics include the mental and neural bases of perception, emotion, learning, memory, cognition, child development, personality, psychopathology, and social interaction. Students will consider how such knowledge relates to debates about nature and nurture, free will, consciousness, human differences, self, and society.

Cette ressource est destinée à toute personne souhaitant développer son leadership. La première dimension de ce dernier est la vision. Une question s'impose : quelle est la vision d'un leader ? Dans cette ressource, la définition de la vision sera débatue dans un premier paragraphe, ensuite la démarche de définition de sa vision est développée.    

Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between the additive and subtractive color systems via predictions, observations and analysis during three demonstrations. These topics help students gain a better understanding of how light is connected to color, bringing them closer to answering an overarching engineering challenge question.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match. Although this is a perception activity, it also demonstrates the difference between mixing colors of light and mixing pigments. Why when mixing pigments does the color darken? How does this differ from mixing colored light? Find out here!

In this activity about light and perception, learners create and observe moire patterns. These special patterns, which appear when two repetitive patterns overlap, can also be used to help learners understand wave interference. Learners will use various objects including pocket combs, window screens, and transparencies to investigate moire patterns in different ways.

Understanding the brain’s remarkable ability for visual object recognition is one of the greatest challenges of brain research. The goal of this course is to provide an overview of key issues of object representation and to survey data from primate physiology and human fMRI that bear on those issues. Topics include the computational problems of object representation, the nature of object representations in the brain, the tolerance and selectivity of those representations, and the effects of attention and learning.
