The Breakthrough Prize honored Deanna and Antonella Sunday at a gala ceremony in Silicon Valley. Each student receives a $250,000 post-secondary scholarship. The science teachers who inspired the winning students receive $50,000. The winners’ schools receive a state-of-the-art science lab valued at $100,000.

The Breakthrough Junior Challenge is an annual global competition for students to inspire creative thinking about science and mathematics. Students ages 13 to 18 from countries across the globe are invited to create and submit original videos (five minutes in length maximum) that bring to life a concept or theory in the life sciences, physics or mathematics. This year 6,000 students from 146 countries entered the competition. The submissions are judged on the student’s ability to communicate complex ideas in engaging, illuminating, and imaginative ways. The Challenge is organized by the Breakthrough Prize Foundation. Khan Academy is a proud partner and helped judge the submissions.

The Breakthrough Prize – Silicon Valley’s premiere science and math prize – honors paradigm-shifting research and discovery in the fields of fundamental physics, life sciences and mathematics. This year, across all categories, the Breakthrough Prize Foundation awards $25 million to honor both outstanding career achievement and emerging talent.

A one-hour, edited version of the gala ceremony honoring winners airs on FOX Sunday, Dec. 18, at 7:00-8:00 PM ET/PT and globally on National Geographic in 171 countries and 45 languages.

The Breakthrough Prizes were founded by Sergey Brin and Anne Wojcicki, Mark Zuckerberg and Priscilla Chan, and Yuri and Julia Milner. Selection committees composed of previous Breakthrough Prize laureates choose winners. Additional information on the Breakthrough Prizes is available at


Announcing our 2016 Talent Search winners in the US and Canada

At Khan Academy, our mission is to provide a free, world-class education for anyone, anywhere. Our mission is ambitious, and we can’t do it alone. We need great explainers to create instructional videos, practice exercises, and reference articles to contribute to our growing library of content.

That’s why we ran the Khan Academy Talent Search again in the US and Canada this June - to find great video creators and amplify their voices. (We’ve also got a talent search in India! Click here for information.) We asked this year’s contestants to focus on a range of subjects from biology and psychology to geography and statistics. We received 1,300 video applications, and were blown away by the quality, passion, and ingenuity.

After reviewing all applications, we selected ten winners: one overall winner and nine finalists.

We were looking for videos that explain academic concepts with clarity and depth, are friendly and conversational, and laser-focused on helping students when they most need guidance - whether they are learning a concept for tomorrow’s test, completing their homework, or reviewing what they learned in class. These 10 videos clearly exemplify these qualities:

Scroll down to see all 10 videos. The overall winner receives a $3,000 cash prize and finalists receive $300. All winners are considered for content creation opportunities at Khan Academy.

Although our talent search is over in the US and Canada, we’re still looking for great creators to bring content to learners around the world. Check out our careers page for current job openings on our content team.  As previously mentioned, we’re running an India Talent Search to identify great video creators who can create content aligned to India’s academic standards.

Check out the 10 winning videos!


Overall winner Alison Caldwell: Doctoral student in neuroscience

Parts of the Brain

Alison’s video description: The brain is a complex organ, and even though it all kinda looks the same, it turns out that different parts of the brain do different things. In this video, we’ll go over all of the major parts of the brain, including the occipital, temporal, parietal, and frontal lobes. And we’ll even cover some of the other structures that get taken for granted. Get ready to fall in lobe!

Why we selected this video as the overall winner: ‘Parts of the brain’ covers the academic concepts deeply and rigorously, and Alison’s delivery throughout the video feels friendly and conversational while staying focused on what a student needs to know for class. You might have guessed that one of the reasons we selected this video as the overall winner is its high production values (engaging special effects, beautiful brain illustrations, etc.). While these certainly make the video enjoyable to watch, high production values aren’t a factor in our scoring. We look for videos that display exceptional clarity, approachability, and a focus on student needs - all qualities this video exemplifies.

Abraham Feinberg: College science teacher and data analyst

Nature vs. Nurture - Part 1

Abraham’s video description: Are your behaviors a fixed, inevitable result of your genes? Or are they the result of the people and objects that surround you? In this video, we’ll take a first look at the concept of Nature vs. Nurture, and we’ll try to get a beginning idea of why it’s such an important issue in many different areas of psychology (and everyday life!).

Alexandra Evans: Policy instructor, Foreign Service Institute

Writing in the Ancient Near East

Alexandra’s video description: People have been drawing pictures for tens of thousands of years, but when did we really start to write things down? How did we develop written words from pictures? In this video, we’ll take a look at the very first writing systems, Sumerian cuneiform and Egyptian hieroglyphs, and we’ll trace how pictures evolved into written words.

Brian Macon: Full-time faculty, full-time father and husband, part-time PhD student

Confidence Intervals and Central Limit Theorem

Brian’s video description: What is the connection between the Central Limit Theorem and Confidence Intervals? In this video we will use a computer simulation to answer that question. The simulation will help us visualize the nature of sampling distributions as we begin our conversation about using estimates to make future predictions.

Jay Lin: Medical student and educational video producer


Jay’s video description: How exactly do drugs affect the brain? This video will go over the normal chemical signaling in brain cells, and then explore the different ways drugs can change this normal signaling.

Kelly Squires: Retired middle school teacher

Plate Tectonics

Kelly’s video description: Whether we’re aware of it or not, the earth’s crust is in a constant state of motion. A whole lot of colliding, dividing and sliding of massive chunks of lithosphere called plates, is happening very slowly but surely, right this very second. The reason for this remarkable movement is plate tectonics. In this video, we’ll explore the cause of plate tectonics, the major plates found throughout the earth and the various landforms such as mountain ridges, valleys, volcanoes and faults that result from the plates’ movement.

Robert Lochel: High school math teacher

Chi-Squared Goodness of Fit Tests

Robert’s video description: Are hospital births equally distributed through the week, or are some days more likely? A chi-squared goodness-of-fit hypothesis test is used to compare the variability present in the data to what could reasonable occur by chance alone, and the big ideas behind these categorical tests are explained.

Check out more videos by Robert.

Finalist: Ron Maxwell: Middle school science teacher

Moon phases explained- middle school level

Ron’s video description: A simple talk to help you learn the phases of the moon and the way the moon phases happen…

Check out more videos by Ron.

Finalist: Sonal Nalkur: Visiting Assistant Professor of Sociology at Emory University

Gender, Norms, and Occupations

Sonal’s video description: Why do some occupations seem to have a higher proportion of men or women? And does a person’s gender always have implications in the workplace? Many sociologists are curious to understand the reasons why the labor market looks the way it does. We also want to understand the specifics about why some people might be excluded or treated differently in the workforce. In this video, you’ll be introduced to some of the concepts that allow sociologists to ask bigger questions about how gender might operate in various occupations.    

Finalist: Steve Yang: Recent graduate of Rensselaer Polytechnic Institute

Bernoulli’s Equation Revisited

Steve’s video description: Engineering principles are often built upon concepts that you may have already learned in math and physics. In this video, we’ll see how we can adapt and expand the energy form of the Bernoulli’s Equation to the hydraulic head form to better suit the needs of engineers.

Usuarios Telcel ahora pueden navegar en Khan Academy sin usar sus datos móviles en las aplicaciones móviles y en, gracias a nuestra alianza con Telcel y la Fundación Carlos Slim // Telcel customers can now access Khan Academy free of data charges on mobile apps and thanks to partnership with Carlos Slim Foundation and Telcel


Estamos progresando continuamente en nuestra misión de proveer una educación gratuita y de clase mundial para cualquier persona, en cualquier lugar. Nuestros contenidos y productos ayudan a millones de estudiantes y maestros alrededor del mundo a practicar y explorar habilidades académicas a su propio ritmo y en sus propios términos.

Sin embargo, estamos a medio camino. Mientras continuamos expandiendo nuestros esfuerzos en los Estados Unidos y en otros países, es importante que nuestros recursos de alta calidad sean accesibles para cualquiera. A pesar de las tendencias globales que indican que las personas están entrando al mundo digital más rápido que nunca antes, todavía existen dos principales barreras para lograr el acceso global a la educación en línea: infraestructura básica y costo de datos de navegación.

En Khan Academy, nos dedicamos a reducir las barreras para el acceso universal a la educación. Hoy, los usuarios Telcel en México pueden navegar en las aplicaciones móviles de Khan Academy en español y en la página sin consumir sus datos de navegación de sus planes de pre pago o pos pago, gracias a nuestra alianza con la Fundación Carlos Slim y Telcel. El costo de los datos de navegación no debería ser una limitante al acceso a la educación básica, que creemos es un derecho humano fundamental.


Da clic aquí para ingresar a los recursos educativos de

Este es el primer esfuerzo en lo que imaginamos puede ser algo más grande: los estudiantes alrededor del mundo con acceso a un tutor gratuito, 24/7, justo en la palma de sus manos. No podremos llegar ahí sin la ayuda de socios alineados a nuestra misión alrededor del mundo. Por eso, estamos compartiendo los principios de nuestro programa de alianzas con un profundo compromiso en poner a los estudiantes primero y estamos emocionados en colaborar con socios que creen que los servicios públicos, como la educación, son críticos para avanzar en el crecimiento humano, económico, y social.

Los principios de la alianza tasa cero de Khan Academy

Estamos colaborando con operadores de telecomunicaciones para que Khan Academy sea tasa cero en dispositivos móviles. Esto significa que nuestros aliados no cobrarán datos de navegación a los usuarios. Nosotros exploramos estas oportunidades de forma puntual. Compartimos y hemos adaptado muchos de nuestros principios directamente de Wikimedia y estamos interesados en desarrollar alianzas y colaboraciones con otras organizaciones educativas sin fines de lucro interesadas en incrementar el acceso en formas similares. Nos regimos por los siguientes principios cuando consideramos llevar a cabo una alianza:

Cláusula de no competencia: El objetivo principal de Khan Academy es proveer acceso a recursos educativos de alta calidad y gratuitos. Estamos interesados en ayudar a organizaciones con la misma misión no comercial de concretar esto

- Los operadores no tienen control editorial de nuestro contenido: El contenido es creado y seleccionado por Khan Academy, en asociación con nuestros aliados. Los operadores no tienen control sobre qué contenido ofrecemos. Ningún operador tiene derechos exclusivos perpetuos

Nuestro objetivo es maximizar el acceso del estudiante, y como tal no ofrecemos derechos exclusivos en perpetuidad a ningún operador, nunca: Esperamos asociarnos con muchos operadores alineados a nuestra misión para maximizar el impacto para los estudiantes

Licencia de uso de marca limitada: Los operadores obtienen una licencia para usar nuestra marca para promover Khan Academy. Ellos no pueden usar nuestras marcas para sugerir que están patrocinados, aprobados o apoyados por Khan Academy

Sin recolección de información personal: Los operadores reciben direcciones IP que serán tasa cero solo para identificar apropiadamente el tráfico en Khan Academy. Los operadores no pueden recolectar información personal acerca de los estudiantes, más allá de monitorear cuáles de sus usuarios están usando Khan Academy.

Sin vinculo comercial: El acceso a Khan Academy a través de programas de tasa cero no puede ser parte de un paquete comercial de un operador

Como una organización sin fines de lucro, nosotros observaremos detenidamente el impacto que este programa tenga en los estudiantes en México. Esperamos poder compartir nuestros aprendizajes. Estamos particularmente interesados en aprender qué tan viables son este tipo de programas durante los próximos cinco a diez años, mientras el costo por datos móviles baje y el acceso a Internet aumente. Por ahora, estamos emocionados en incrementar el acceso de una forma pequeña pero importante para los estudiantes en México.

Los usuarios Telcel en México ahora pueden navegar en Khan Academy en dispositivos móviles a través de o en nuestras aplicaciones para Android y iOS llenas de ejercicios, videos y artículos de un amplio rango de materias. Este trabajo no hubiera sido posible sin el generoso apoyo de nuestro socio, la Fundación Carlos Slim y Telcel. Para ingresar a más contenido educativo de calidad y sin cargo de datos visita

We’re making continual progress toward our mission of providing a free, world-class education for anyone, anywhere. Our content and products help millions of students and teachers around the globe find, practice and explore academic skills at their own pace and on their own terms.

But we’re only part way there. As we continue expanding our efforts in the US and beyond, it’s critical our high-quality resources be accessible to everyone. And despite global trends that indicate people are coming online faster than ever before, there are still two major barriers to equalizing global access to online education: basic infrastructure and the cost of data.

At Khan Academy, we’re dedicated to reducing barriers to equal access to education. Today, Telcel customers in Mexico can access Khan Academy’s mobile apps in Spanish and the website without consuming data from their pre-paid and post-paid plans, thanks to partnership with Carlos Slim Foundation and Telcel. Data costs alone should not limit access to a basic education, which we believe is a fundamental human right.

This is the first effort in what we imagine can be something bigger: learners around the globe with access to a free, 24/7 tutor, right in the palm of their hands. We won’t get there without the help of mission-aligned partners around the globe. As such, we’re sharing our program principles to signal both our deep commitment to putting learners first and our excitement to collaborate with partners who believe public services like education are critical for advancing human, economic and societal growth.

Khan Academy Zero Rating Partnership Principles

We’re collaborating with telecom carriers to zero rate Khan Academy on mobile devices. This means our partners sponsor data charges to make them free for learners. We examine these opportunities opportunistically. We share and have adapted many of these principles directly from Wikimedia and are interested in developing partnerships and collaborations with other education nonprofits interested in increasing access in similar ways. We abide by the following principles when considering a partnership:

Non-competitive clause: Khan Academy’s main goal is to provide access to high-quality educational resources free of charge.  We’re interested in helping ensure organizations with the same non-commercial mission can do so as well.

Carriers do not have editorial control of our content: Content is created and curated by Khan Academy, in association with our partners. Carriers have no control over what content we deliver. No carrier has perpetual exclusive rights.

Our goal is to maximize access for the learner, and as such we do not offer exclusive rights in perpetuity to any carrier, ever: We hope to partner with many mission-aligned carriers to maximize the impact for learners. 

Limited trademark license: Carriers get a license to use our trademarks to promote Khan Academy. They cannot use Khan Academy trademarks to suggest they are sponsored, approved, or endorsed by Khan Academy.

No collection of personal information: Carriers receive the IP addresses of sites that will be zero-rated only to appropriately identify Khan Academy traffic. Carriers cannot collect personally-identifiable information about our learners beyond monitoring which of their users is using Khan Academy.

No commercial bundling: Access to Khan Academy through zero-rating programs cannot be part of or combined with a carrier’s commercial bundle.

As a non-profit, we will be closely watching the impact this program has on learners in Mexico. We look forward to sharing what we learn. We’re particularly interested in learning how viable these kind of programs will be over the course of the next five to ten years as the cost of data declines and access to the Internet increases. For now, we’re thrilled to increase access in a small but meaningful way for learners in Mexico.

Telcel users in Mexico can now access Khan Academy on mobile devices via or our Android and iOS apps, complete with exercises, videos and articles across a wide range of subjects. This work would not have been possible without generous support from our partners, the Carlos Slim Foundation and Telcel. To access more great educational content completely free of charge, visit

Khan Academy adds apps for young children


We’re excited to announce that Duck Duck Moose, an award-winning developer of educational apps for young children, is now part of Khan Academy.

We believe every child should have access to the best learning resources, so we’re making all 21 of Duck Duck Moose’s apps free.

Download the apps for Android from Google Play

Download the apps for iPhone or iPad from the App Store

Early childhood learning is a natural next step for Khan Academy. It allows us to reach children at a younger age and begin to have an earlier impact on basic literacy and math skills. We’re thrilled to enter early childhood learning with Duck Duck Moose as our partner. We’ve long admired their whimsical children’s apps, which have been downloaded more than ten million times and receive rave reviews.

In addition, Duck Duck Moose’s nine-person team is joining Khan Academy to lead a new initiative to develop early learning products for young children. This is possible thanks to philanthropic investment firm Omidyar Network, the first underwriter of this new initiative. Like us, Omidyar Network believes early childhood education is critical for long-term success. Together we hope to have a lasting impact on the lives of children.

We’re thrilled to welcome Duck Duck Moose to the Khan Academy family, and we hope you love their apps as much as we do.
