    Introduction

    Have you ever found yourself daydreaming about attending MIT, one of the world’s most prestigious universities? The thought of learning from top-notch professors and delving into subjects like science, engineering, and humanities can be incredibly enticing. Well, here’s some exciting news: you can now get a taste of that prestigious MIT education without the hefty tuition fees. It’s all thanks to Free Online Courses Offered on MIT OpenCourseWare (OCW), an open and free platform offering a treasure trove of educational materials from over 2,500 MIT courses¹.

    In this blog post, let’s embark on a journey to discover what OCW is all about, how it functions, the perks it offers, and how you can start your own learning adventure with MIT, all for free.

    What is OCW??

    OCW stands for OpenCourseWare, and it’s essentially a digital treasure chest brimming with materials from thousands of MIT courses that span the entire curriculum. This means you can dive into lecture notes, exams, videos, assignments, and various other resources from any MIT course that catches your interest. Moreover, you can explore collections of courses tailored to specific subjects, such as Africana Studies, Energy, Entrepreneurship, Environment & Sustainability, Introductory Programming, and much more¹.

    Unlike typical online courses, OCW liberates you from the constraints of registration, schedules, and deadlines. There’s no need for formal interactions with instructors or fellow learners, and you won’t be opening your wallet for any fees or certifications. With OCW, you’re the captain of your learning ship, charting your course at your own pace and in line with your individual goals and passions.

    OCW is a self-directed learning experience that grants you access to MIT’s vast wealth of knowledge and expertise. Whether you’re looking to enrich your personal understanding, advance professionally, undertake academic research, or even educate others, OCW provides the resources you need.

    How to Get Started with OpenCourseWare

There, you can explore courses by department, topic, or keywords. Plus, there’s an advanced search feature to help you filter courses based on factors like level, language, format, features, or instructor.

    Once you’ve found a course that piques your interest, clicking on it reveals the course’s homepage. Here, you’ll find a concise overview including the course’s description, objectives, prerequisites, requirements, syllabus, schedule, and details about the instructors. Most importantly, you’ll have direct access to a variety of course materials, ranging from lecture notes and videos to readings, assignments, exams, solutions, projects, labs, simulations, software tools, and more.

    Feel free to download any materials for offline use or future reference. Alternatively, you can conveniently view them online using your web browser or mobile device. Keep in mind that certain materials may require specific software or plugins, so it’s a good idea to check the technical requirements listed on each course’s homepage.

    Moreover, OCW offers some unique features that can elevate your learning journey:

    • OCW Educator: This portal allows MIT instructors to share special insights into how they use OCW materials in their teaching, offering valuable pedagogical insights¹.
    • OCW Supplemental Resources: Dive into some of OCW’s richest educational content, including open textbooks, video tutorials, interactive simulations, online games, podcasts, and more¹.
    • Chalk Radio Podcast: Gain a behind-the-scenes look at MIT faculty’s innovative teaching methods and course creation in this engaging podcast¹.
    • OCW YouTube Channel: Discover millions of educational enthusiasts on MIT Open Learning’s YouTube channel, where you can watch lectures, demonstrations, interviews, animations, and more².

    A Living Computer: Designed and Programmed

    Introduction

    A Living Computer: Designed and Programmed by scientists from MIT and Technion. The genetic sequence of the plasmid was designed to operate as a basic artificial neural network, or more precisely, a basic computer. The procedure entailed introducing genetic material into a bacterial cell in the form of a plasmid, which is a small DNA molecule that stays apart from the “natural” genome of the bacteria. The study team was able to explicitly construct and program a basic artificial neural network using the many function plasmids that are known to exist freely in nature. This was accomplished by having multiple genes on the plasmid control each other’s activation and deactivation in response to external inputs.

    How can a computer be biological? What does it really mean, a living cell, a circuit?

    In the simplest form and explanation, a computer consists of 0s and 1s, of switches. Operations are performed on these switches: from summing operations to getting the maximal or minimal value between them, etc. And the more advanced operations are built upon the basic ones, which made it possible for a computer to play chess or fly a rocket to the moon without human involvement. Imagine, the possibility of what biological computers can do then, through scientists having designed and programmed a living computer (or perhaps rebellion)?

    In “electronic computers,” transistors form the 0/1 switches. Our cells, on the other hand, are also computers, albeit of a different sort. Biologically, the presence or absence of a molecule can act as a switch. Genes are activated, triggered, or suppressed by other genes, forming, modifying, or removing molecules. Synthetic biology is a branch of biology that aims to harness these processes as well as synthesize the switches and program the genes that would allow a bacterial cell to perform complex tasks. Living cells are equipped naturally to sense chemicals and produce organic molecules within its environment. The scientists embarking on the challenge of being able to “computerize” these processes within the cell could have major implications for biomanufacturing and have numerous medical applications.

    Conclusion

    The group scientists designed and programmed the living computer were Ph.D students were Luna Rizik and Loai Danial (now doctors) together with Dr. Mouna Habib. They worked under the guidance of Prof. Ramez Daniel in the Faculty of Biomedical Engineering at Technion Institute. And in collaboration with Prof. Ron Weiss from the Synthetic Biology Center, MIT, were wowed and inspired by how artificial neural networks function. They collectively created synthetic computation circuits by combining existing genetic “parts,” or engineered genes, in novel ways, and implemented concepts from neuromorphic.
