On one unforgettable occasion, Maruyama Sensei was visiting Rutgers dojo . In our new location we had to walk the gauntlet of the weight training room to get to the practice space. Thirty-odd young men were lifting huge metal plates on various machines and sweating profusely. Three or four of us trouped through in our gi, feeling rather small in the presence of all that unadulterated muscle. I muttered something about how Sensei was still the strongest man in the room.

In an earlier post , I wondered, "Is ki real?" Is ki an actual thing, or is it just a concept? I teach aikido to college students. So I hesitate to write about science as if I know anything, because I know I will be challenged! But I offer this: Only a small part of the electromagnetic spectrum is visible to the human eye. We are all familiar with ultraviolet and infrared rays or waves and the ways in which they can be used: gamma rays, X-rays, infrared heat lamps, microwaves, and radio. Infrared light was only discovered by humans in 1800 and ultraviolet in  1901 . But animals such as bees  and snakes  have sensed these parts of the spectrum for eons. How might a snake's ability to find prey or a bee's ability to find nectar have been described or understood before we had instruments to perceive these wavelengths? Dark matter  is a discovery that has only recently become known to non-scientists. Only 50 years ago, in popular culture at least, dark matter
