    “A scientist studies what is, whereas an engineer creates what never was.”

           – Theodore von Kármán[1]

    The National Academy of Engineering carries the flag of the engineering profession in the United States. But when I asked the ...

    The digital twin concept involves simulating the future performance of a specific product or system based on current knowledge about the system and how it is operated. Key aspects of the concept include near- and long-term performance predictions individualized to both the particular product/system ...

    Editing the genetic code of living organisms with word-processing-like capabilities has been a goal of life scientists and engineers for decades. For biomedical applications, changing as little as a single base in the 3 billion bases of the human genome might cure disorders such as muscular ...

    The annual incidence of vector-borne disease exceeds 1 billion globally—roughly half of the world’s population is at risk of infection.[1] Mosquito-borne diseases account for the majority of cases (WHO 2014), but there are no vaccines for most of them, so prevention, mainly through ...

    Biology is the most powerful known manufacturing “technology.” Proof of this is all around: at the continental scale, the Earth’s land surface is defined by plant life, much of which has been harnessed with agriculture. At the nanoscale, biological systems routinely self-organize ...

    A revolution is underway to reengineer the blueprint for life: the genetic code, whose sequence determines identity and function for every living organism. The genome (expressed in DNA base pairs) is the entire complement of an organism’s genetic code and is housed in the basic functional ...

    Autonomous vehicles (AVs) raise a host of ethical challenges, including determining how they should interact with human drivers in mixed-traffic environments, assigning responsibility when an AV crashes or causes a crash, and how to manage the social and economic impacts of AVs that displace human ...

    Society is rapidly advancing toward autonomous systems that interact and collaborate with humans—semiautonomous vehicles interacting with drivers and pedestrians, medical robots used in collaboration with doctors, or service robots interacting with their users in smart homes.

    A key aspect of ...

    Bitcoin was introduced in 2008 as a computer protocol establishing a decentralized system that allows users to hold balances and make transfers to one another (Nakamoto 2008). Computer systems that provided similar services have existed for decades, but required a trusted party to control and ...

    Higher education in engineering in the United States has been driven by engineering science since the Second World War, geared toward in-depth understanding of engineering science for long-term benefits. The model -proposed by Vannevar Bush, recommending more emphasis on science in education to ...

    I am extremely pleased to see that as of the spring 2019 issue of The Bridge a new EES Interface column has been added. This collaboration with the NAE’s Center for Engineering Ethics and Society is an excellent development. It offers thoughtful perspectives, sometimes slightly different from ...

    In architecture, fundamental concepts such as aspect ratios—how the width of a structure relates to the height—matter a great deal. But Sir Ove Nyquist Arup interpreted them broadly. For him, such elements were only a component of “total design.” He believed that structures ...
