The cluster looks like a star to the unaided eye and appears close to the easternmost star of the Southern Cross, ( Beta Crucis ), so is only visible from southern latitudes.

To the unaided eye, a more prominent star such as Sirius or Arcturus appears larger than a less prominent star such as Mizar, which in turn appears larger than a truly faint star such as Alcor.

If the patient can perceive figure kinesthetically when he cannot perceive it visually, then, it would seem, the sense of touch has immediate contact with the spatial aspects of things in independence of visual representations, at least in regard to two dimensions, and, as we shall see, even this much spatial awareness on the part of unaided touch is denied by the authors.

# unaided by the Holy Spirit, no person is able to respond to God ’ s will ;

Sometimes it is possible to " see " anagrams in words, unaided by tools, though the more letters involved the more difficult this becomes.

In as much as patients can throw themselves into the nervous sleep, and manifest all the usual phenomena of Mesmerism, through their own unaided efforts, as I have so repeatedly proved by causing them to maintain a steady fixed gaze at any point, concentrating their whole mental energies on the idea of the object looked at ; or that the same may arise by the patient looking at the point of his own finger, or as the Magi of Persia and Yogi of India have practised for the last 2, 400 years, for religious purposes, throwing themselves into their ecstatic trances by each maintaining a steady fixed gaze at the tip of his own nose ; it is obvious that there is no need for an exoteric influence to produce the phenomena of Mesmerism.

Since the capabilities of such intelligence would be difficult for an unaided human mind to comprehend, the occurrence of a technological singularity is seen as an intellectual event horizon, beyond which events cannot be predicted or understood.

The simplest way to communicate is through ‘ no technology ’ or " unaided " methods in which the individuals with RTT indicates a response ( i. e., points, blinks their eyes, raises their eyebrows ) to indicate a response.

Possibly he proposed 87 ° as a lower bound since gauging the lunar terminator's deviation from linearity to 1 ° accuracy is beyond the unaided human ocular limit ( that limit being about 3 ° accuracy ).

Before the advent of sport climbing in the United States in the 1980s, and perhaps somewhat earlier in parts of Europe, the usual style of unaided rock climbing was what is now referred to as " traditional ".

NP-complete problems do not tend in their general case to be easier for unaided humans than for suitably programmed computers: it is doubtful that unaided humans would be able to compete successfully against computers in solving, for example, instances of the subset sum problem.

Indeed more than six centuries passed before the idea was again resuscitated ; and even then it required a group of brilliant Frenchmen to do what the old Dominican had carried out unaided.

It has been observed that the unaided human eye can generally not differentiate detail beyond 300 PPI ; however, this figure depends both on the distance between viewer and image, and the viewer ’ s visual acuity.

In making the case for the anomaly, he gathered and interpreted data from a wide variety of sources, including first-hand accounts from extant historical observations of the Sun going back to the telescopic observations of Galileo and other contemporary scientists of the 17th and early 18th centuries ; from historical reports of the aurora borealis observed in past centuries in Europe and the New World ; from visual observations of sunspots seen with the unaided eye at sunrise and sunset in dynastic records from the Orient ; from existing descriptions of the eclipsed Sun ; and from measurements of carbon-14 in dated tree-rings.

The outlines of the design are further touched up and emphasized with silk or woollen thread of different colours run round the finer details ; the stitch used for this is at an angle overlapping darn stitch, all the stitches used are so minute and fine that individually they can be seen with the unaided eye only with difficulty.

Nothing is more obvious to-day than the signal inability of capital and private enterprise to take care of themselves unaided by the state ; and while they are incessantly denouncing " paternalism ," by which they mean the claim of the defenceless laborer and artisan to a share in this lavish state protection, they are all the while besieging legislatures for relief from their own incompetency, and " pleading the baby act " through a trained body of lawyers and lobbyists.
