lunar crater data latitude 50.8 N or S N longitude 163.9 E or W E diameter 248 km depth Unknown colong 201 eponym Jean le Rond d Alembert Jean d Alembert D Alembert is a large Moon lunar impact crater located in the northern hemisphere on the Far side Moon far side of the Moon , to the northeast of the somewhat smaller walled plain Campbell lunar crater Campbell . Astride the southwest rim of D Alembert is Slipher lunar crater Slipher . To the north is the crater Yamamoto crater Yamamoto , and to the south southwest lies Langevin crater Langevin . This walled plain has the same diameter as Clavius crater Clavius on the near side, making it one of the largest such formations on the Moon. As with many lunar walled plains of comparable dimensions, the outer rim of this formation has been worn and battered by subsequent impacts. Besides Slipher, the most notable of these craters is D Alembert Z intruding into the northern rim. There is also a small crater on the northwest inner wall that has a wide cleft in its eastern side, and a smaller crater along the southeastern inner wall. As eroded as the rim may be, its form can still be readily discerned as a roughly circular ridge line in the lunar terrain. The interior floor of D Alembert is a relatively level surface, at least in comparison with the rough terrain that surrounds the crater rim. It is marked with a number of small crater impacts, the largest being D Alembert G and D Alembert E toward the eastern rim. In the southwest, the floor is more irregular due to the outer wikt rampart rampart and layers of ejecta from Slipher. A pair of shallow clefts in the floor surface radiate away from this crater, beginning near the mid point of D Alembert and reaching half way toward the inner wall. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater mid point that is closest to D Alembert. class wikitable width 25 style background eeeeee D Alembert width 25 ... more details

In special relativity , electromagnetism and Wave wave theory , the d Alembert operator represented by a box math scriptstyle Box math , also called the d Alembertian or the wave operator , is the Laplace operator of Minkowski space . The operator is named for French mathematician and physicist Jean le Rond d Alembert . In Minkowski space in standard coordinates t , x , y , z it has the form math begin align Box & partial mu partial mu g mu nu partial nu partial mu frac 1 c 2 frac partial 2 partial t 2 frac partial 2 partial x 2 frac partial 2 partial y 2 frac partial 2 partial z 2 & frac 1 c 2 partial 2 over partial t 2 nabla 2 frac 1 c 2 partial 2 over partial t 2 Delta. end align math Here math scriptstyle g mu nu math is the inverse Minkowski metric with math scriptstyle g 00 , , 1 math , math scriptstyle g 11 , , g 22 , , g 33 , , 1 math , math scriptstyle g mu nu , , 0 math for math scriptstyle mu , neq , nu math .

Lorentz transformation s leave the Minkowski metric invariant, so the d Alembertian is a Lorentz scalar . The above coordinate expressions remain valid for the standard coordinates in every inertial frame. Alternate notations There are a variety of notations for the d Alembertian. The most common is the symbol math scriptstyle Box math the four sides of the box representing the four dimensions of space time and the math scriptstyle Box 2 math which emphasizes the scalar property through the squared term much like the Laplacian . This symbol is sometimes called the quabla cf . nabla symbol . In keeping with the triangular notation for the Laplacian sometimes math scriptstyle Delta M math is used.

It is here that he introduces his theory on life and nature, indicating that matter is not fixed but that, on the contrary, subject to evolution . Each species in existence transforms itself and gives birth to a new species. He would later create a special version for his patroness, Catherine the Great Catherine II of Russia, replacing the certain character names.
