Online education is on the rise in the US and abroad and provides a convenient form of knowledge transfer to people who cannot be full- and or even part-time students at community colleges or universities. This factor impacts industry representatives, displaced workers, and low-income learners. Usually, online education consists of online lectures and/or tutorials designed so users can comprehend the studied subject. The missing piece of online education is the lack of hands-on activities. To address this issue, Michigan Tech and West Shore Community College collaborate on researching, developing, and implementing a State-of-the-Art Teleoperated Robotic Workcell (TRW) to enable enhanced remote training for industrial robots. The system is designed to provide training opportunities to college students, industry representatives, and displaced workers wishing to retool their skills and become more competitive in the job market. 

We studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 using r -band light curves and UV-visible to near-IR spectra from the first 11 observational seasons after its discovery. The 2009−2019 light curves displayed pronounced microlensing variations on different timescales, and this microlensing signal permitted us to constrain the half-light radius of the 1930 Å continuum-emitting region. Assuming an accretion disc with an axis inclined at 60° to the line of sight, we obtained log( r 1/2 /cm) = 15.4 −0.4 +0.93 . We also estimated the central black hole mass from spectroscopic data. The width of the C  IV , Mg  II , and H β emission lines, and the continuum luminosity at 1350, 3000, and 5100 Å, led to log( M BH / M ⊙ ) = 8.6 ± 0.4. Thus, hot gas responsible for the 1930 Å continuum emission is likely orbiting a 4.0 × 10 8   M ⊙ black hole at an r 1/2 of only a few tens of Schwarzschild radii.
