bakterid organismi sattuda. Köögiuks ei ole õnneks nii must, et seal bakterid vohada saaks. Sellegipoolest tasub kindlameelselt käte hügieeni meeles pidada, mine tea, millal võib see ukselink kord bakterite monopoliks saada. 8 Kasutatud kirjandus [1] Fredrickson JK, Zachara JM, Balkwill DL (2004).

some directions than others. That was true for supernova 1987A, recorded 20 years ago, the closest and brightest supernova since 1604. Astronomers also have found that some of the neutron stars left behind by supernovas zip along at 500 miles a second (800 kilometers a second), as if the explosion had imparted an enormous kick in one direction. Stronger evidence for the sound wave idea could come from two sprawling facilities, in Hanford, Washington, and Livingston, Louisiana, designed to detect gravitational waves--ripples in the fabric of space and time. Gravitational waves, predicted by Einstein's theory of general relativity but never directly observed, should be produced whenever immense masses shake and twist, as they do in the core of a supernova. If sound waves really are at work inside a collapsing star, it should vibrate only at certain frequencies, generating matching gravitational waves
