A cozy autumn setting with a lit candle, warm beverage, stacked books, and scattered leaves.
Nestled among a collection of old, worn books, a warm cup rests on a knitted blanket, emitting a sense of warmth and comfort. A lit candle adds a soft glow, enhancing the cozy atmosphere. Nearby, a small pumpkin and fallen leaves hint at the autumn season, while the background features a rustic bookshelf overflowing with literature, suggesting a quiet corner perfect for reading and relaxation. This scene captures the essence of fall and the pleasure of quiet, introspective moments spent indoors.
Figure 1: Kiptily and colleagues [3] observed fusion reactions in a donut-shaped vessel called a tokamak (gray). The red, blue, and pink balls represent protons, neutrons, and electrons, respectively. In each fusion reaction, a deuterium nucleus (one proton plus one neutron) merged with a tritium nucleus (one proton plus two neutrons) to generate a free neutron and an alpha particle (two protons plus two neutrons). The free neutron escaped the tokamak, whereas the alpha particle remained inside the vessel and heated electrons that spiraled along magnetic-field lines (green).
