sun time vs clock time     it is due to  i) the plane of the Equator is not the same as the plane of the Earth's orbit around the sun, but is offset from it by the angle of obliquity, and ii) the orbit of the Earth around the sun is an ellipse and not a circle, and the apparent motion of the sun is thus not exactly equal throughout the year.   Positive values when a sundial appears faster compared to a clock showing local mean time; negative when slower   sundials uk oarval wiki  usno navy mil archive codeproject in c# wikipedia

Stir the milk to dissolve the sugar Remove the milk from water bath, and let milk cool down to 60 deg C ( zingibain is most effective at 60 deg C)  If temperature is 70 deg C or higher, zingibain protease will be denatured. pour  ginger juice to bowl pour milk at height of 20 to 30 cm above the bowl don't stir the mixture! and let it rest for 20 min   Zingibain wiki Khymos Protein and fat content

  計劃2021年上半年發射空間站核心艙，而後接續發射天舟二號貨運飛船和神舟十二號載人飛船。目前，核心艙已經基本完成測試的全部工作，航天員乘組已選定，正在開展任務訓練。 在海南文昌用長征五號B遙二火箭發射空間站核心艙。計劃4月２９日發射 4月12日 中國載人航天工程辦公室12日透露，執行天舟二號貨運飛船發射任務的長征七號遙三運載火箭完成了出廠前所有研制工作，日前已安全運抵文昌航天發射場。 　　據介紹，長征七號遙三運載火箭將與先期已運抵的天舟二號貨運飛船一起按計劃開展發射場區總裝。 2021至2022年，中国载人航天工程预计将实施包括空间站核心舱、实验舱、载人飞船和货运飞船在内的11次发射任务。 中国运载火箭技术研究院负责长征二号F、长征七号、长征五号B运载火箭的研制工作。根据计划，长征二号F、长征七号、 长征五号B三型运载火箭将分别承担载人飞船、货运飞船和空间站核心舱发射任务。 Tianhe天和一號 is planned to be inserted directly into a low Earth orbit with an apogee of 340 to 450 kilometres. and inclined by 41 to 42 degrees.  The plan is to have three astronauts on board for six-month stints, and Tiangong will be able to accommodate up to six astronauts during crew transfers. Tiangong will consist of three modules. Tianhe will be the core module that will provide the living quarters for the astronauts as well as the command and control centre for the space station. Meanwhile, the Tiangong-1 and Taingong-2 modules will be the space laboratories from which all e...
