Microarcsecond VLBI: What will We See?

Reductive evolution towards primitive life: What will we see?

Observing the gradual transition from “life” to “non-life” tells us a lot about the features of living systems. Based on this idea, we started simplifying natural cells by inactivating their genes randomly through experimental evolution. Escherichia coli (E. coli) cells were cultured in a high-mutagenicity environment to accumulate replication errors on their genomes. As a result, we observed d...

On What We See

This paper investigates the idea that perception can be, at once, a mode of direct awareness of the world and an encounter, in the first instance, with mere appearances. In developing this point, I introduce a sensorimotor account of perception according to which the senses are ways of exploring the environment mediated by different patterns of sensorimotor contingency (i.e. by the distinctive ...

What we don't see.

Copyright © 2012 Massachusetts Medical Society. Sixty-eight years after the inaugural issue of The New England Journal of Medicine and Surgery, Sir William Osler introduced the term “pediatrics.”1 Although “diseases peculiar to children” had figured in Benjamin Rush’s lectures at the University of Pennsylvania since 1789, most physicians in the early 19th century did not recognize children as a...

Knowing What We See

Have you ever wondered how you know what you see? For example, when you see a round, red object at the grocery store, how do you know that it is called an apple and that it can be eaten? This type of knowledge is called semantic memory. Semantic memories are learned over a lifetime and can be accessed without remembering a specific experience. In other words, you do not need to remember details...
